Giant Torus? A Joke?

It's real. How many beads are used in this model? What is this model corresponding to? How long does Chuang spend in making this model?

It is not hard to imagine that in a multilayer graphitic system, it is likely to have many holes connecting different sheets in the system. This picture in fact stands for the simplest situation.

Another possibility is the carbon Riemann sheets. Chuang has written a matlab program to generate this type of carbon systems. If I find the code, I will post it later. Maybe he can do it himself. Unfortunately, we don't have the beaded model for this kind of material yet. I probably have to find an undergrad to help me.
