Post its!

These two things are both made out of the simple polyhedral piece.
The first - Moving Cubes:

First make 16 cubes

hook them together (this is harder than it looks) make sure they are opposites

Build

Make them move

This one is 90 units. This is made out of 3X3 post its (the super sticky kind unfortunately they made it harder to fold the pieces because the sticky would tear the paper.)

 This next one is made out of the same units, it is 120 units and is made out of 2X2 post it notes. (My mother doesn't buy post its unless they are odd shapes now because this is what happens to them...)
