Looking but can't remember

[Glidr]

I'm looking for a short animation I saw on the net a few years ago. I can remember it but I can't for the life of me remember the title.

It was 3D but looked as though it was 2D. It was this weird ninja fighting these three men in a street. One of the men had this superfast kick and they ended up fighting on top of a yellow bus. The ninja thing kicked the asses from these guys.

At the end the ninja guy/thing pulled this super power move thing and punched this guy and left a sort of bowl/crater effect in a wall. It was awesome.

Please help me, I'm going insane trying to find it on the net.
