One of the first thoughts to come to my mind upon booting up Limbo was "how long until someone turns this into a LittleBigPlanet level?" Not long at all, it turns out.
A user by the name of bra2008 (fantastic name, by the way) has a map that is, essentially, Limbo in LittleBigPlanet. Not only in grayscale aesthetics, but also in subject matter -- some of the puzzles are ripped straight out of the source material.
Part two is supposedly on the way. I hope bra2008 is able to incorporate brainslugs somehow.
