This object is known the Penrose Triangle or Penrose Tribar, after Sir Roger Penrose, the mathematical physicist (and recreational mathematician who created it. Dutch artist M. C. Escher was interested in mathematics and used this impossible mathematical shape twice over to create his lithograph "Waterfall" in 1961. Can you see where and how it is used? After figuring that out, you might want to check out the wild video on YouTube posted below Escher's work.
