I've been experimenting with updating the firmware on my MakerBot Replicator 2, to make it easier (and more accurate) to change filament mid-print (and thereby change color). There isn't a lot of documentation so it isn't easy, but it's possible, and that's what makes this so cool.
So have you / are you planning to watch Cosmos? I'm not a TV watcher - at all - but I was intrigued by this series after reading a glowing New Yorker article about Neil deGrasse Tyson, the new emcee.

Sounds like they're off to a good start: I wish them well; there are so few channels to expose the man on the street to the majesty of science.
