One of simplest optical illusions to create is the thaumatrope.  No doubt you have seen the bird and the cage thaumatrope at some time.  It is a disc on a string with pictures on each side depicting something which, when spun, combine into a single image.

My eldest wanted a dinosaur eating, my youngest a dog.  On a bit of an olde Victorian theme today.  My eldest has just run inside with a feather asking for a piece of paper and some ink.
