Have a clear, maybe plexy glass, half pipe so that people could watch the trick biker/skateboarder do there tricks from an interesting view point. The promoter could sell more seats and the people that buy the seats would see tricks all around them.

       This would be fun. For the first few runs anyway. Any thoughts on how to keep it from getting scratched to the point of opacity?

       great idea. here is a croissant. are you talking about bellingham, washington?
—zpprhed, Dec 21 2002
   

       nevermind, yes it is bellingham. nice

       [half] You'd probably have to have something akin to a Zamboni come in and polish the surface of the plastic every so often, to avoid scratches ruining the view. There are fine abrasive pastes that are designed to polish plastics, they are often used when refurbishing cell phones and other devices with displays for resale.

       Toothpaste works well to polish plex.

       Why are half-pipes straight?   

       I'd have though that a slightly conical half-pipe would give a better audience view and allow more creative use of the kinetic/potential energy balance.

       arrange it like the all-around aquariums at seaworld and the like...i'd go! very cool, +

       Yes I agree, you should have a device for polishing every surface. A maser would do well for that acrylic, but keep the audience away.

       //Please enlighten this poor Brit!// Go get a job like the rest of us!

To answer you question, a half-pipe is literally that, a "half of a pipe". It is used by skateboarders, bladers (rollerskaters), snowboarders, morris-men to create gravity-defying tricks.
