Escher Optical Illusions Revised

So this is one I've used forever... but this year wanted to add a little something more to it.  Here is my past post for my optical illusions and power point with tutorial which is super easy for subs to use and they always turn out great:  http://artjulz.blogspot.com/search?q=optical

But this year... I wanted to go a little deeper.  Unfortunately testing hit and classes started getting canceled and I didn't get to do it the justice I really wanted...  but the concept is still there.

The students did their optical illusions as usual...then we added our Escher twist.  They traced their hand, made observations and drew the front and back of their hand exactly like their own.  Next they cut them out.  I took their photos and they cut them out in a sphere shape.  They had to create their own composition of where their hand should be place and how they should arrange their fingers to make it look as realistic as possible.  Some were great...some were good attempts.  But overall they loved them which is the most important! They also love my books!
