I have been doing a bit of research on mechanical toys and automata. Several books and many youtube videos later I am feeling confident enough in my knowledge of cams and crank shafts to start on my first art piece including motion. But before I did I wanted to make one of the projects from a book David bought me for Christmas called Gizmos by Rob Ives.
This is the book along with the paper toy I made today with the punch out paper parts provided. I think it took about two hours to sort it all out. The mouse flys back and forth while flapping his arms. Amazing.
