Here are some T-shirts, a couple based on autologlyphs and some other mathematical designs. I'm using Spreadshirt.com, which lets you upload designs to their website, they deal with all the printing, shipping etc., and I get a small commission on each sale.
The designs are a bit difficult to see on their site, so there are larger versions of the designs with a few details lower down on this page. You can also put these designs on other kinds of clothing, tote bags etc., as well as choose your own colours and so on here. The prices depend in part on how many colours are used in the printing.
Create your own shirts/tank tops/bags etc. with these designs here.

(Jan 2009) This is the smallest solution to the problem of taking a square and dissecting it into a number of smaller squares, such that all of the smaller squares are of different sizes, in the sense that it requires the fewest number of smaller squares, 21. It was discovered by A. J. W. Duijvestijn in 1978. |
|
(July 2008) Third iteration of the Peano-Gosper space filling curve, with some extra added edges in the lower right to close off the path. From a Mathematica notebook with some editing in Illustrator. |
|
(June 2008) The figure 8 knot, rendered in Rhino then traced in Illustrator. |
|
(June 2008) 5 tetrahedra arranged within a dodecahedron, also one of the stellations of the icosohedron. Designed in Rhino then imported into Illustrator. |
|
(June 2008) Based on a spiral I've used elsewhere, generated and Voronoi diagramed in Mathematica. Colouring of nodes is based on the mod 2 and mod 3 values of the number of the node. |
|
(June 2008) Another colouring scheme, this time using a "metric" on the natural numbers, based on how many Fibonacci numbers you need to add together to sum to the number. Here the white nodes are the Fibonacci numbers themselves, light blue is 2 Fibonacci numbers, dark blue 3 and red 4 or more. |

(June 2008) A vector version of an autologlyph from 2002. |
|
(June 2008) Another updated autologlyph. |
