Impossible Teaser 2

Mr. Gogo, 513 pieces.  (See below for more--in my "I'll try anything once, twice if I like it, three times to make sure" approach I have 2 different versions.)  As always a delightful puzzling experience, with pieces that are just pleasant to hold and some interesting spaces created by conjunctions.  The repeating pattern added to the challenge--the three different layers have the same image, but different sizes and some two-layer connecting pieces.  7/10

Impossible Teaser 2, 458 pieces.  Different piece count; basically the same great puzzling experience. 7/10
