Courtesy of hand-crafting superstar Moxie, here's a Katamari Damacy playset for the real world, made of little else but felt and magnets.
Look at it go! Not only does it work pretty well (so long as you're trying to pick up small metal objects), but that rendition of the game's classic theme song is enough to put a smile on even the crankiest sausage's face.
Katamari Damacy was first released on the PS2 back in 2003, and has since appeared in a number of titles and re-releases on systems like the Xbox 360, PS3 and PSP. You can see a gameplay demo of the game here.
