Tesseract

The tesseract, or hypercube, is the 4D cousin of the everyday 3D cube. Consisting of eight cubes folded onto each other in four dimensions, the tesseract is often projected into our 3D world as a cube within a cube with edges connecting them. This is another vector image only available on Spreadshirt.

Impossible Cube

Impossible cube design is available in two styles. Since Spreadshirt only allows for three color choices in vector designs there is one with two colored sides and black edges and another with three colored sides and no edges.

Infinity

Infinity symbol with a fade. Available as a vector design so you can choose your own color on Spreadshirt. This one only has one color to pick but the specialty colors (like glow in the dark!) only allow you to use one color anyway.

DNA Circle

A double helix linked back upon itself to form a circle of DNA. Available as a vector design so you can choose your own color combination on Spreadshirt. Vector designs are only available on Spreadshirt so that's the only place I'm selling this one.

This is the first of several vector images designed specifically to take advantage of Spreadshirts special printing techniques. So far it's the only Print On Demand site I've found that can take .eps files and allow users to choose their own color combinations or to have glow in the dark or metallic prints available. If you know of any that I don't, please, please, Please let me know in the comments. I always like to have some new options.
