Anybody got any really crazy tricks they can do,

one i'm working on is a nose wheelie, spinning the back wheel backwards, setting it down and doing a backwards 360

I'd also like to powerslide 180 and end in a trackstand, a friend of mine can do it on a fixed gear krate bike, but i'm not sure it's possible on a big track bike.

Also can anybody ride straight backwards, like how BMXers ride fakey>
