This lizard is a lot of fun. It's constructed with modules that are connected with a "hingelike" mechanism. You can wiggle the lizard holding its tail or its head, and it will dance for you!.
The lizard was designed by Tomoko Fuse. The diagrams can be found in the book
The New Origami
, by Steve and Megumi Biddle.
I folded it with twelve 3" (75 mm) squares of floral colored origami paper.
