The Zoatron is an experimental creature builder: you type in a name, word, or anything you like, and it makes a model: a zoa.
If you see one you like, you can get a plastic model at Shapeways for under $20, or download the printable 3D file for free. If you get it from Shapeways I receive $1, and you receive my eternal gratitude.
I had so much fun writing this, and they cheer up my desk like anything. If you print one, I'd love to see a photo.
The same word will give you the same zoa...until the engine evolves. If you see one you like, safest to download or print it now.
This requires WebGL, which some browsers don't support (looking at you Internet Explorer) and older graphics cards may not have. I'm sorry for the exclusivity. I chose this method because it works well enough that I think it may become the standard.
