Moving illusions: Impossible objects made real



“The artist M. C. Escher was renowned for creating drawings of imaginary spaces that could not exist in three dimensions. Or could they?

Kokichi Sugihara at Meiji University in Kawasaki, Japan, has been using computer software to bring impossible drawings to life. The video above shows some of the objects he has made moving in ways that appear to defy geometry.

When the models are turned around, however, the trick is revealed: the objects are not what they seem. That’s because we constantly make assumptions about perspective and depth in order to move about in a 3D world, and these models take advantage of those assumptions.

Sugihara used computer software to analyse seemingly impossible drawings and come up with solid shapes that might look like the drawing from one perspective, but not from others.

It’s not the first time Sugihara has tricked New Scientist readers with his illusions. Earlier this year, the engineer won first prize in the 2010 Illusion of the Year contest in Naples, Florida.”
