13 August, 2013I've made a
sea shell tessellation. It has rotational symmetry, and it's built around equilateral triangles. Each seashell is an equilateral triangle, and each set of three shells creates a larger equilateral triangle.
5 August, 2013I've made a 3rd version of my Escher-style shark tessellation. This latest version looks much more alive-- less stiff and stuffed than the 2nd version.
25 July, 2013I've created a 2nd version of my Escher-style shark tessellation art. This new version is much more seamless than my 2011 original. The older version had shamelessly large gaps between the tiles (sharks). A proper tessellation should have "no gaps nor overlaps".
15 July, 2013 Angela Aycox's 2012~2013 4th grade class math class from Zaneis Elementary School in Wilson, Oklahoma show off their Escher-style tessellation art.
4 July, 2013 Only a month after the first batch, we have a new batch of tessellation art from Ms. Widya Huang's 4th grade math class in Batari
School, a small school located in Medan, Northern Sumatra, Indonesia.
5 June, 2013 Look at the new tessellation art from the 4th grade classroom of Ms.Widya Huang, a math teacher from Grade 4 in Batari
School, a small school located in Medan, Northern Sumatra, Indonesia. She shows us Escher-style tessellations made by her eight 4th grade students. I think this is the first time a school outside the USA has given us tessellation art.
24 May, 2012 Zaneis Elementary School of Wilson, Oklahoma proudly displays its make-your-own Escher-style tessellation art in our newest guest school gallery ...just before going on Summer Vacation, and probably forgetting allll about us... *snif-snif*. Or maybe those kids will spend their summers honing their art skillz???.
21 April, 2012 Ms. Suzette Mitchell's 7th grade gifted math class in Coosa Middle School, Rome, Georgia, in the U.S.A. made some fun Escher-style tessellation art. Check 'em out, then make a tessellation yourself!
13 March, 2012 Many thanks to 8th grade math teacher Tammy Rahn, who wrote and asked me to fix the broken menu link to our large Tessellation Animation gallery. D'oh! I wonder how many weeks it lay there broken, frustrating you visitors while I remained unaware of the problem. The fix was just a few taps on the keyboard, so PLEASE, if you see something on this site that doesn't work, or should be better, let me know!
12 March, 2012 Artist Bruce Bilney's gallery has been expanded from just 1 to about 15 fun tessellating patterns.
18 December, 2011 The banners at the tops of Tessellations.org pages are now animated. Love it? Hate it? Is it too distracting during class, teachers? Tell me. You can turn the animation on and off by passing your mouse (cursor) over it. The default start state is "yes, animate the banner." Passing your mouse over the banner then turns animation off. To then reanimate the banner, you can either reload the webpage (CRTL-R) or let your mouse again hover over the banner. Experiment to see how it works.
9 December, 2011 I'm an idiot. Since childhood I've been looking at the candelabras used for the Jewish holiday Hanukkah, and at Escher's art for the same long time, but only now did it occur to me that a menorah and its buddies can tessellate very well. Be on the lookout for my next tessellation, "dradels!" ...Oodles and oodles of dradels.
11 July, 2011 Famous Australian tessellation artist Bruce Bilney lets us animate his tessellation of kangaroos. Expect more of Bruce's art on Tessellations.org in the future. Computer boffins will enjoy learning that this GIF animation weighs only 18 kilobytes. That's light.
29 June, 2011 Chess pieces fit together nicely. With very little adjustment, they make a fine tessellation. I can't believe it hasn't occurred to anyone else yet. I've been checking with other tessellation artists and with chess enthusiasts. So far, we've found a handful of chess knight tessellations and some rather modern non-standard chess sets that tessellate, but nothing done with the entirety of a standard chess set.
25 February, 2011 - "Tessellation or not?" a new section of this website. For a long time, I've wanted to write this section, but couldn't find enough artists willing to show their beautiful but (possibly) non-tessellation art on my site. This section teaches "what is a tessellation?" by example. You look at several pieces of symmetry art, and decide whether they fit the definition of a tessellation. Examples come from kids, me, a pro photographer, and David (the first webmaster here).
10 September, 2010 - A delightfully Halloween-appropriate ghost tessellation by guest artist Mike Maloney. These're such friendly-looking white and orange ghosts. I can easily imagine this pattern becoming commercially successful on Halloween party paraphrenalia.
16 July, 2010 - Tessellations are all around us: Tessellations are in the news, in nature, in our homes and cities. Teachers, show your students our gallery of "tessellations all around us". Then, for homework, ask your students to find and list as many tessellations as they can find in their homes, in a supermarket, in a park, school, forest or shopping mall. Exceptional examples from your students may be posted in this gallery.
16 April, 2010 - Sometimes you type a www...com address, or click on a link, and things don't work right. The Internet can't find the webpage you're looking for. At times like this, the Internet computer you've reached tells you "404: I can't find the webpage you requested. Is it spelled right?" Those messages are sometimes very unfriendly and difficult to understand. That's why I wrote my own 404 message page for Tessellations.org.
14 April, 2010 - One more art class has volunteered to post their tessellation art on Tessellations.org. Welcome, Karen Weber's 4th grade art class from Saint Ignatius Loyola Regional School in Pennsylvania.
10 October, 2008 - The way Tessellations.org originally defined tessellation drew scholarly criticism because it seemed to preclude designs (like the Moorish designs in the Alhambra of Spain) made from purely geometric shapes like squares and triangles. Our definition of tessellation seemed to insist that the design must use more natural, realistic shapes like plants, animals, and people. I agree with the critics, so Tessellations.org now defines true tessellation as "filling any surface completely with a repeating shape, with no gaps or overlaps". Notice that in our definition, the surface needn't be an infinite plane, nor even a 2D surface. In the future, I plan to show many more tessellations on 2D non-infinite surfaces and on 3D objects' surfaces. I would like also to encourage you to contribute copyright-free photos of the geometric tessellations appearing in Middle Eastern art and the Alhambra.
25 September, 2008 - Five Cat Dodecahedron by Seth: a simple 12-sided 3D object. Easy to print out and glue together. Each facet is a pentagon with 5 cats tessellated on it.
24 September, 2008 - Kitchen Floor Tile Tessellation, an amazing home improvement made from 1,300 handmade ceramic tiles! By Mr. Dick Walton and Mrs. Susan Newell of Billings, Montana, and their potter friend, Jim Morrison.
23 September, 2008 - Clown Ball, a 3D tessellation by Seth of 12 clowns drawn on the sides of a "dodecahedron", a sphere made of twelve pentagons.
19 September, 2008 - Fascination, a tessellation by Seth of baby seaturtles and bats.
18 September, 2008 - Liquid World, nostalgia for a summer spent at the seashore...and fountain pens. A tessellation by Seth.
6 May, 2008 - Tessellations.org today lost its founder and original webmaster, David Annal. This comes after three years
of successes battling cancer, during which time he continued to contribute art and coding to this site, and to develop
other art websites such as ApophysisStash.org, a fractal art website.
His generosity, intelligence, and art will be greatly missed.
A tessellation contest is planned in his honor. The site will continue under webmaster Seth Bareiss
1st January, 2008 - A brand new type of gallery: tessellations from a school's students, submitted by the schoolteacher and posted on our site as a single school's gallery. Have a look at DECTC school's tessellations. Does your school have tessellations you'd like to show in our galleries? Let us know!
20th December, 2007 - Fish evolving? A fun cartoony tessellation by Seth.
17th December, 2007 - Our first tessellation tutorial from a guest artist! See the Papercut Method by 15-year-old Rachael G.
13th February, 2007 - Added a new animation-- a short film, this time-- to our animation gallery.
This is a film of one of Seth's goldfish tessellation balls, showing the various
Al Hirschfeld-style cartoon faces.
See it here.
12th December, 2006 - A new review of an old, popular standalone tessellation program,
18th November, 2006 - How about an aquarium with fish that tessellate? See
14th November, 2006 - Tessellations with Lego? Yes indeed, check Real Materials here.
And I've added another animation of kite flying
11th November, 2006 - This weekend I've made a new animation, Dancers. ~Seth
8th November, 2006 - I've also done a new animation, Crebain Spies,
remember the crow-like creatures who spied on the members of the
Fellowship of the Ring? And there are two new tessellations in my art
gallery 7 ~David
8th November, 2006 - In addition to asking you to contribute your art to our
we encourage child and adult artists to enter
World of Escher's free tessellation contest.
This popular Internet contest has been held every six months for over a
decade. Entering costs nothing; prizes vary, but are always from World
of Escher's online store.
More importantly, entries are displayed in a high-profile contest
gallery for six months, during which time everyone is invited to visit
the site, vote for a favorite, and leave positive comments for favorite
entries. The top few entries apear in a permanent
hall of fame.
Entries should be in the form of emailed JPG files
less than 100 kilobytes, and must be accompanied by
a simple entry form.
Entries can be made by computer
or by hand, but must be original designs and be the work of the
contestant whose name appears on the form. Although in the past the
majority of past contestants and winners has been schoolchildren, World
of Escher tells us that adult entries are increasing; if more than 15
adults enter the coming competition(s), then World of Escher will
create separate divisions (and awards) for children and adults. ~Seth UPDATE: The WorldOfEscher.com website ceased its contests in late 2011. Our website, Tessellations.org, will revive them in the second half of 2013. ~Seth
25th October, 2006 - Our 3rd birthday is on 30th October!
To celebrate, David has given the site a shakeup and, even better, Seth
has agreed to become joint owner/editor/manager 8-). This means
changing the 'David's Art ' references throughout the site to 'David's
and changing Seth's status from guest artist.
Major changes are the
new 'Software' section in the main menu, and the fledgling 'Animation'
section under Galleries. Tessellation software will be reviewed and
tested and opinions given. To begin with it contains 3 programs with
several examples from each. Purpose software has been removed from the
DIY section. There is only one animation at present but it will grow!
David has also started gallery 7!
10th October, 2006 - 1 new tessellation ("4-and-twenty blackbirds") in Guest Artist Sethness Gallery 3
25th September, 2006 - 3 new tessellations in 'David's Art 6'
5th September, 2006 - A few minor updates and improvements.

as actual quilts, carvings and anything else that can be held! If you
have made anything like this, please send a photo for inclusion here.

12th February, 2005 - Teachers
- I have removed the tessellation of a nude woman! It was completely
innocuous but when I put her in, I did not realise how popular the site
would become with teachers of young children. It is now indexed by many
2nd February, 2005 - I
have added another section to the 'Do It Yourself' menu to answer some
'Frequently Asked Questions'. The first ones deal with flipping and
periodicy. There are more good contributions to the guest gallery too.
26th January, 2005 - At last someone has sent me a new tessellation for the guest gallery - thanks Pete.
26th December, 2004 - Added 1 more tessellation to David's Art 5.
17th December, 2004
- Added another tessellation to David's Art 5. Shame on you many

received. Perhaps your teaching is not as good as you thought it was!
11th June, 2004 - Added 2 more tessellations to David's Art 5 and a "Desert Scene" to My Nice but not True gallery.
21st May, 2004
- Began David's Art 5 with 2 new tessellations. Many of you promised to
send in your tessellations for the guest gallery but few have. Perhaps
my explanations were not as good as I thought and you keep telling me??
29th April, 2004
- David's Art 4 is now full. Many schools are looking at the site and
are very welcome but, because the guestbook is open to all, I'm afraid
it's getting some 'silly' messages from some of the less well educated
pupils 8-( I'm removing these as soon as I find them
and I'm sorry if you see one before I've clobbered it!
5th April, 2004 - Added 3 more tessellations to David's Art 4.
13th March, 2004 - Added more to David's Art 4. I'm amazed at how popular this site has become - almost 2 million accesses
since it started! Perhaps I'm doing something right 8-) Thanks
everybody - but the Guest Gallery could do with some more pictures!
21st February, 2004
- Added this page. Added new DIY section - Multiple Motifs. Added
example of this, 'Siameses', to 'David's Art 4'. Brought index of pages
up to date.
15th February, 2004 - Yahoo
chose this site as a 'Pick of the Day' - thanks! Able to welcome many
new visitors and read their comments in my guestbook. Thank you to all
who filled it in (only a fraction of those who came though). I am now
eagerly awaiting their contributions to my guest's gallery which is
still very bare in spite of new bear 8-)
Since the site opened in October 2003,
several people have asked for permission to use pictures in books, on
sites, etc. This is mostly quite OK by me (and I'll even give it to you
in high res. if req) but please ask before you swipe anything - and
give this site a plug or, even better, a link! Any site linking will of
course be given one back. ~~David Annal
(note: This policy has changed a bit. Please email us to arrange any borrowing / copyright /
permission to reproduce our art. ~~ Seth Bareiss, webmaster in 2011)
I try and check everything but if you do find any mistakes please let me know - see 'contact' in the 'Site Information' menu.
