puzzle like thing

This is a puzzle like thing where you draw 1 square at a time

instead of looking at the picture like a hand or a face or what ever. 

Say I had a picture of a hand and I am copying the hand on to another piece of paper 

and I do the hand and I think thats not right then I would turn the hand or change the hand.

So this is changing that, its making it so you have to trust yourself and do it 

good enough to actually make the picture look real.

(not that mine look's real)
