This is a mobius strip of Level 1 or Super Mario Bros. The whole level is wrapped around itself in a single surface, and poor Mario begins and ends at the same spot every time :(

All the elements from the level are there: every mushroom, turtle, cloud and star. They are all carved out of the surface at different heights, which looks fantastic when you have a light coming from the side, and each block casts a shadow.

It's a great piece to have on your desk, or to hang from a string to let it spin around.

Interlocking gears in a steampunk theme. These standard sized gear dice will keep your game turning (figuratively speaking, they do not actually turn...)

With percentile die.

This detailed model of the moon is hollow and therefore very price efficient. It will balance on a small gap on the bottom. You can also hang it on a wire using a bent paperclip. See video and images. Made for full color sandstone.

This is a cookie cutter, it can also be used for clay or Play-Doh.

Higher resolution version of the firebug model. Shapeways can't print this, but you can make one for yourself on any home printer. Here's the file: http://www.thingiverse.com/thing:11683 - now why don't you get yourself a printer and start making things?

X-Wing Model Without Stand. Length: 100mm

This model was inspired by the "restraining bolt" used in Star Wars, by Jawas to prevent their droids from wondering off. Multiple can be stacked, or a magnet (such as http://amzn.com/B000SJ61EC) can be glued into the bottom. This model is hollow. A solid version is also available.
