From the MAKE Flickr pool:

Flickr user fdecomite built this impressive rhombidodecadodecahedron (say that three times fast). Impressive! There don’t seem to be any build details available, but surely there has to be a geometric figure papercraft model generator somewhere… right?

Update: Francesco chimed in to point out that he designed the model using Magnus J Wenninger’s book Polyhedron Models.
