Via Steven I find this, a machine that will create solid 3-dimensional shapes out of sugar. I wonder if the machine can stand minor impurities like dye and flavoring? This could be a very cool sort of novelty gift. Just provide a LWO, DXF, or 3DS file and make your friend a big ‘ol hunk of candy in the shape of your choosing. It would be a lot more exciting than a cake with their name on it.
Me? I’d make myself a giant set of edible geek dice. But you knew that.
A Klein Bottle would be a cool thing to make as well, and it would be a lot easier than the crazy steps they have to take to make them out of glass. Sadly, it would lose some of it’s appeal since it would probably be opaque.
