you should try a mini me jr - i think its going to be so much fun.
the green optical illusion is about 5 feet square.
the tute i'll be making for the optical illusion is about 25 inches square.
then you can connect as many of them together as you like.
the one i'm working on is 4 panels, so thats 50 inches, set on point in the center.
then i'll put a border around it, followed by 1/2 optical panels to square it off.
then another border or 2 - i'm aiming for somwhere between 6-7 feet in size.
