I found this model of buckyball created by the 3D printing technique through googling a few weeks ago. It is cool. One can simply print a 3D molecular structure with a 3D printer. I wonder how much it would cost to have a printer like this and how much it would cost to print a model.
It is worthy of mentioning that this model is not a beaded structure. In fact, I believe it is not possible to create a beaded structure with this kind of connectivity by using the standard beads with a single hole. The beads we normally use should represent the edges, instead of vertices of a graph.
