The Incredible Expanding Bunny optical illusion

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.

Grow You Own Magic Mushroom optical illusion

Grow You Own Magic Mushroom optical illusion

This is an amusing way of dressing up the optical effect when a person stares at the centre of a rotating spiral disc for 20 seconds or so. When the person then looks at the magic mushroom, it appears to grow or shrink, depending on which way the spiral was rotated. Made in China for Worldwide co, npw.co.uk.
