Whilst looking for the moving spirals illusion that i posted in the daily pics thread I came across this illusion. Personally I just thought it was so good I'd post it as well. The comments in the picture says it all and believe me I printed and cut the squares out, they are exactly the same colour.
Had seen some like relativity, waterfall and Drawing hands, but I've just had a better look at some of his works. Among others I quite like Hand with reflecting sphere thanks for the tip. :smilie:
One of my favorites. It has always amazed me how he could create such intricate drawings, fooling the viewer, without going a little nutso while he was at it.
