Butterfly ball

One of the club members brought this in to volunteering and we were trying to put it together for the longest time.  It didn't work.  I went home with the pieces and tried to assemble it myself, and I got it to work.  Hooray!
The basis behind the name of this origami is that when you throw it up into the air, as it falls apart, the pieces are supposed to look like butterflies.  It took me several tries to get the air shots, but you get the general idea.

Sorry about my arm, haha.
