Ah, the tesseract. It's a fourth dimensional cube thingie, so actually it's an abstract shape. Strictly speaking, as they taught us in kindergarten, it's a convex regular 4-polytope but who's counting.

Actually, glass is very neat stuff (as is water) and one could make an entire career studying it.
