Diabolical Pyramid Puzzle... And a BONUS

This puzzle was described on my Instructables page,

>http://www.instructables.com/id/A-Diabolical-Puzzle/<

but since I've been having such a great time giving these away to strangers, I'm adding it here.

The idea is to make the 2 pieces into a pyramid. It can be done, but it's not as easy as you might think. A great ice breaker.



Update:

AdanA took cymon's comment about cutting the pieces in half and ran with it:
