perpetual motion

Myself and Sam, my friend and work colleague, just spent a few hours trekking around San Jose's Tech Museum of Innovation, which, fittingly, considering we are dead-hot in California's Silicon Valley, is all about computers and what not.

The museum, like all museums, is unremittingly ace; we watch an amazing film about the Louisiana wetlands in the imax cinema, then make turbines, design rollercoasters, look at old computer chips and ride (virtual) bobsleighs. Best of all, however, is a massive rolling ball sculpture by George Rhoads, which occupies us for a half an hour, examining the route of the tumbling billiard balls and plotting their trajectory, as well as attempting to capture the motion, on my slow camera.
