Sonic X Reanimate (Fan Animation)

I'm sure most Sonic fans have seen this already, but I thought it deserved a shout-out:

Original

A bunch of animators put together a "reanimate" of the (English) Sonic X episode "Cracking Knuckles" (mostly known for its Sonic/Knuckles fight scene). Almost 300 animators banded together to make it, and the constantly changing result is both awesome and comedic. Clips can be viewed on their creators channels, and the whole episode can be found Bilianna's.
