This take on the classic "impossible triangle" or "Penrose triangle" illusion uses dice to create the appearance of an object that is fundamentally impossible in ordinary Euclidean space.

First devised by mathematician Roger Penrose this illusion is created from several separate parts that when viewed from a certain location produce the appearance of the triangle.

This image of coloured spirals appears to be moving if you stare at it, however in reality it is completely stationary. One of the most impressive moving illusions we've ever seen.

Warning: Sensitive observers should exercise caution when viewing this image.

This impressive illusion by Shigeo Fukuda is sure to boggle the mind. On the right we can see a strange structure made out of various piano parts and shapes, yet when viewed in the mirror on the left the reflection is of a completely normal looking piano.

The illusion works because the parts are arranged in such a way so as to produce the reflection of a perfect piano when seen from one specific viewpoint.

Move anywhere else and the reflection won't work.
