DIY physics: A spark chamber on a steel tower, for no reason.

Gigabit Switchman writes: Slightly deranged hoopy frood (and artist) Douglas Ruuska has convinced a bunch of folks to help him build a functioning spark chamber (which is pretty cool, high voltage FTW), and then to put it on top of a steel tower covered with a few kW of addressable LEDs. Because that totally makes sense. The particle detectors will output data to a BeagleBone that controls the LEDs, and the design is being open-sourced once it's functional. Details at the story URL. (They're also running a Kickstarter, but I'm not linking that.)
