If someone wanted to make a lot more Escher/video game mash-ups, we'd be perfectly fine with that.
M.C. Escher's art featured things like staircases that march ever upwards -- or downwards, depending on how you look at it. Artist Chris Carlson demonstrates Escher's staircase beautifully by combining it with video game icon Donkey Kong. The staircase builds up into an impossible loop that is demonstrated when DK tosses a barrel that falls down until it returns where it started.
