Magnet Mario
No, it's not a new ability in Super Mario Galaxy. And no, it's not a funky Mario/Mega Man fusion-type thing. Over 1,500 fridge magnets make up this gigantic Mario Mosaic constructed by Annie Rush. The image took over 12 hours to complete, which is far more time than I'm willing to put into anything that doesn't involve me, food, and me eating the food. Annie plans to tackle Van Gogh's Starry Night next, which will be a tad more difficult than 8-bit Mario.
