The Incredible Expanding Bunny optical illusion

This is a fun application of a well known optical illusion. If you spin the disc clockwise on a table and look at its centre for around 20 seconds, and then look at the bunny sitting nearby, the bunny will appear to increase in size. Spinning the disc anti-clockwise will make the bunny look smaller. Made in China for Worldwide co, 3 Warple Way, London.
