Maybe I'm just easily amused (hell, I know I am), but I get a distinct jolt of delight every time someone makes something clever in LittleBigPlanet. Bring anime into it, however, and you're really prying at my weak spots -- I'm a sucker for such things. For instance, seeing this video and getting a glimpse of Kaneda's legendary bike from anime classic Akira had me laughing aloud and yelling "TETSUOOO!" in my apartment while my cat looked at me with bewilderment.
The commenters seem to think that this could have been created by the same user who made the Gradius level, but it wasn't confirmed. I hope this guy (or gal) continues to make cool stuff, because watching it is truly a pleasure for this nerd.
