I haven't forgotten...

...that I said I was going to take a stab at Tom Hull's five intersecting tetrahedra origami design and document the hilarity for blog prosperity; at this point, I've only completed one of the five frames, but look this weekend for a pictorial update, and most likely a lot of crumpled paper.

BTW, another reference for this design is the out-of-print-but-still-available Origami Handbook by Rick Beech.
