TesselMania!™ is a stand-alone tessellation creation program.
It will run under DOS, Windows 3.1 ~ WinXP, and Macintosh (68030, 68040 or Power Mac system 7.1 or later).
Its drawing toolkit is only slightly less comprehensive than MS Paint
(the pixel-based drawing program that comes with MS Windows).
These tools and the tools specific to tessellation are above average for a standalone tessellation program.
However, users accustomed to the extensive toolkits in powerful drawing programs like Adobe Illustrator, Photoshop, Paintshop Pro,
and GIMP may feel frustrated by working with Tesselmania!'s comparatively small toolkit.
Those graphics power-users may prefer to look for tessellation plug-ins for their favorite graphics-drawing programs.
Of special note to Windows users: It will work under Windows 95
through XP, though its Windows compatibility shows signs of
near-obsolescence. Most Windows users will have to tweak the desktop shortcut's compatibility properties to make it run.
We do not expect it to run under Windows Vista.
- tessellation tiles can be resized and reproportioned.
For example, if your design starts out as a brick-like outline,
you can make that brick's height, width, tilt, and height/width
proportions change as you draw. This massively useful feature is
strangely lacking in many other tessellation programs.
- fairly complete drawing toolkit. There're
a"floodfill/paintbucket", several line widths, and a (slightly large)
eraser, all of which are tools strangely missing from many other
- The color palette is a little awkward, but includes many
more color variations than the 8~16 colors offered by many other
tessellation programs. There's also a selection of pattern-fills,
a feature uncommon in tessellation programs.
- You can click on several buttons which will show the
current tessellation in several entertaining automatic animations.
These animations are NOT savable or distributable without clever use of
a 3rd party screenshot program.
For this review, I captured one of these animations easily using the shareware screencapture program "SnagIt",
and then converted that data into an AVI video and an animated GIF. You can see
that GIF here (300k).
- You can view and edit the design in several different sizes, at the click of a button.
- The program goes to extreme lengths to assist you while you
choose a tessellation pattern. This is a vast improvement over
the somewhat cryptic tile-pattern menus in other programs. The
help here includes examples, colorful arrows, and short animations.
- Without special setup, this program won't run on PCs that
display more than 256 colors. The setup isn't difficult,
however:right-clicking on the desktop shortcut and set Windows'
compatibility-setting to pretend that the PC can only display 256
colors at a time.
- "Save" is limited to a unique proprietary format, *.TSS.
Therefore, to export your picture to another program, you must
either use the EDIT >> COPY command (which copies the picture to your
Windows clipboard), or hit the "printscreen" key on your keyboard to
copy the current contents of your screen to the Windows Clipboard, use
a screenshot program like
SnagIt, or use a printer and
scanner. (To get something OUT of the clipboard again, use the
destination program's "EDIT >> PASTE" feature. "PASTE" puts
a copy of the Clipboard's contents in whatever program you're using at
- File names and directory names are limited to the old DOS
8.3 filename.ext rules, and "My Documents" may be difficult to find if
you're new to Windows.
- You will be unable to run or switch to almost all
other programs while running Tesselmania.
programs are a lucky exception. As a result of Tesselmania's limitations,
all programs will be in 256-color mode
until you exit TesselMania.
- Smooth outlines are not possible, although you can approximate them
by using several sharp corners with tiny angle changes.
This is a "sharp" contrast to most other tessellation programs,
which usually allow sharp and rounded corners.
- Although you can toggle back and forth between "single
tile" and "completed pattern" at the click of a button, you can only
edit the picture while looking at a single tile on an empty background.
This can hinder you as you toy with a pattern.
- The "undo" tool only allows you to undo the ONE most recent
action. That limitation was the most annoying problem during
testing, though it's somewhat compensated by the presence of an
- You can only work on one design at a time.
- The help menu is somewhat limited, and the advice written
in it is often clipped-off in mid-sentence because of Windows
compatibility problems. However, I've seen worse help menus in
To create a tessellation, one must start by choosing a vague pattern
from a menu of flips, rotations, and offsets. This can be the most
daunting area for a newcomer, though TesselMania makes a heroic effort
to explain the choices by offering examples and diagrams.
The next step is looking at a simple shape (square, rectangle,
triangle, hexagon) on a plain white background. In this stage,
it's tempting to go straight to the drawing tools, but I don't
recommend it. Instead, use the arrow and pushpin tools at the top
of the menu bar to distort the shape of the basic tile. Leave the
drawing and coloring for later.
In this stage, you can resize and reproportion the tile... a feature
that I greeted with a happy sigh, because it seems so essential yet
it's missing from the vast majority of other standalone tessellation programs.
Thank you, Tesselmania!
Without this feature, all your rectangles are squares; drawing a
tall, thin tessellation is impossible; all your cats and snakes will be short and fat.
To manipulate the outer edge of your tile, use the arrow-shaped tool
for resizing sides and sliding the image left, right, up, and down.
Use the pushpin -shaped tool to click on the borderline, thus
creating a "turning point", rather like putting a pin into a string.
Also use the pushpin to drag existing "turning points" to new
locations. Use the scissors-shaped tool to remove "turning points".
The three main tools you use in this stage will only
work in "normal viewing size". They will not work
when you click on the "view large version" buttons (x2, x4, x8), so wear your reading glasses.
Now you can optionally begin filling in the interior of the tile with
lines, color-fills, and patterns. If you choose to adjust the
outline of the tile during this stage, notice that the interior does
NOT squish, expand, or move to match the altered outline.
Once your tile is finished, click on a button to see the completed
pattern. Notice that many of the repeating tiles will be in
colors that you didn't choose. Yellow parts of your original
design, for example, will become bluish purple in some of the other
tiles. Let's call this the "anti-pattern". The reason for this
"antipattern" is so that it's easy to see where one tile stops and the
neighboring tiles begin. You may have to experiment to find
colors that look good even in Tesselmania's anti-pattern. This color
distortion is neither optional nor adjustable.
Once you're done making a pattern, you choose how to save your masterpiece.
If you plan on working on this pattern again in TesselMania, then use FILE >> SAVE.
However, in its free "trial" version, the FILE >> SAVE menu will only
allow you to save in Tesselmania's unique *.TSS format, which is
incompatible with all other programs of any type.
The lack of a JPEG, PNG, GIF, EPS, AI or other common picture format is a
serious intentional shortcoming in the free trial version of TesselMania.
The free version which Tessellations.org reviewed did not say what file formats are available in the non-free
version, but I expect they include GIF and do not include *.PNG.
To save the picture in the more traditional formats, you can print it out
or use a Screenshot to copy-and-paste the picture into another program
like GIMP, Adobe Photoshop, Adobe Illustrator,
PaintShop Pro, OpenOffice, MS Word,
Powerpoint, or any of a hundred other programs, and then save it.
I tested this technique, and had no problem using the PrintScreen key on my keyboard to copy
the entire current screen, then paste it into a few other
programs...even better, I'm happy to report that I was able to easily use
(a feature-rich screenshot program)
to record one of TesselMania's built-in animation features as a movie file.
Those animations are some of Tesselmania's most unexpected and entertaining features.
See my recording of one here.
How do we rate this program? Good, but not consistently good.
It's an average of some very good features and some outdated or weak features.
A big "plus" is the large number of
companion books available for it.
Although we haven't had the opportunity to review those books yet, and therefore can't vouchsafe their quality,
their existence seems a good sign that TesselMania is (or was) a well-respected program.
Learning to use the program doesn't require any reading, but the
interface is occasionally confusing and requires some
experimenting. Even experienced PC users should not expect pretty
results in their first three attempts. You can get basic
results quickly, but fine tuning the outline is difficult.
Initial setup (installation) is simple, but will not explain how to set up compatibility
with Windows versions beyond Win98. For that, please consult Jill Britton's webpage (listed at the end of this article).
If this software gets updated in the near future and upgrades a few
features, we can expect it to be very popular. Without a rewrite,
however, I do not expect it to run under Windows Vista, which premieres in
2007. Inexperienced Windows users may be frustrated by dealing with
its reliance on very old Windows and hardware standards.
On the other hand, if you're using an older PC, this will be a blessing--
it can run on a PC with as little as Win95, Win3.x, or DOS 5.0, 256-color display,
less than 5 megabytes of RAM and less than 10megabytes of free hard disk space.

Jill Brixton, the famous tessellation teacher, has written a number of
companion books. We hope to someday soon post reviews of those books here at Tessellations.org .
There are several books about Tesselmania (and used versions of Tesselmania on CD)
There is a separate but similarly-named product on the market called
"TesselMania! Deluxe" It appears to be by the same author and to include many more kid-friendly features,
but we have not been able to locate a copy for review.
If you know where we can find a copy for review or where copies are being sold, please
A single tile at the start.
The white and black diamonds are handles and turning-points. They can be dragged to resize, reshape, and reproportion the
tile's outline. Clicking on a line with the "pushpin" tool creates a new turning point; clicking on a turning point
with the "scissors" tool removes that point.
TesselMania!'s extensive color palette and fill-patterns.
Note the up- and down-arrows at the right.
Clicking on them reveals many, many more options.
TesselMania!'s resize buttons.
Not all tools will work in 2x~8x modes.
TesselMania!'s three unique and entertaining
automatic animation buttons.
Clicking on this button
converts your single-tile image to
a repeated tile pattern that fills the entire screen.
TesselMania!'s limited, primitive "save" menu.
Note the use of short, restrictive DOS-style "8.3 filename.ext" filenames.
Also be aware that the free downloadable version will ONLY allow you to save and load images in TesselMania!'s
unique *.TSS format.

Notice that the text is cut off along the right-hand side.
There is no way to view the missing text.
Above is my completed tessellation, drawn within TesselMania!.
Note that the chesspieces alternate darkbrown/lightbrown/darkbrown.
This color alternation is automatic, but the user cannot select what each color's alternative might be.
So, for example, some of your frogs may look green while the others look purple, blue, or red!
