I'm a huge fan of the power of user created content, and there's few games out there as supportive of UCC as the Trackmania series.

Case in point, the game allows for people to create, showcase, share and even sell content to other users. In the showcase category, I stumbled across a nifty clip within the Youtube-like Trackmania portal from Ptitnono999.

Some very cool stuff.

I hope people make stuff half as cool as this when we ship Flock! and its full editor in the next week or so. :)
