Impressive Optical Illusions Sketched Out by Hand

Nathan Cox is a British comedian and artist who creates really impressive optical illusions using just pen, paper, and a ruler to sketch out a deliberately blurry image. Cox then runs a black lined, semi-transparent sheet over the top of the sketch to make whatever he’s drawn appear to move.

…Nathan creates his amazing optical illusions by passing a layer of black paper, which contains striped gaps, over his drawings, to help make them come to life.
