Why stationary?

If you mount your desk to a non-stationary bicycle and then use it for 8 hours, I'd like to see YouTube video of it.

... you should probably plan to take the video in the first few minutes. After that it'll probably be a moot point.

The "Conference Bike" is not quite the same thing as a non-stationary bike desk, but it still insane. (Google has some of these.)

*"The ConferenceBike is pedaled by 7 riders sitting in a circle. One person steers while the other 6 pedal (or not) as the bike moves effortlessly along."

The beer bike is probably more popular:

Well... that's my point. I'm suggesting blendergasket does it, not me. That would be crazy.
