Actually, long before I purchased the goldsprints setup, I was thinking about ways of combining the raw physical exertion of goldsprints with artistic expression. Those ideas are kind of scattered, (attach paintbrushes to the rollers somehow? Gigantic bike-controlled Etch-a-Sketch?) but one of them is pretty coherent and simple to set up:
Who's with me? I have to admit, I'm not much for slam poetry, but we could even do it with readings if people feel like improvising lines while their heart rate is in the 180's is going to be too hard.
And I'll get to work on that giant Etch-a-Sketch idea.
