Well this illusion we knocked up a bit quick hence the graphics are not very good. But if you like it we will do a better version in the future. Anyway we have produced two versions because we know some of you can't see the 'Flash' animation on your iphone or ipads.
The idea is our take on Escher's box from his famous 'Belvedere' painting shown here on the right. We have made a few changes for good measure and then animated the colors on the sides just to screw with your brains. Enjoy.
