Impossible Stairs

3D-printed exoskeletons, free Getty, Play-Doh Oscars and more in our weekly look at the web

Calling to mind the warped realities of artist M.C. Escher, Lionel Penrose and his son Roger have created a new variation on their Penrose Triangle. This endless staircase is a 2D depiction of steps that make four 90-degree turns; in essence meaning a person will always be climbing on a loop, but never get any higher. The artwork is housed in Munich, but because of the laws of nature, it will never exist in three dimensions.
