Here's a FREE paper model of a dragon (optical illusion) with a head that seems to follow you around when you move about. You simply cut the pattern, glue or tape it together, and put it on a table or any flat surface, then move around and watch it's head follow you. This paper model is downloadable as a PDF file.
