Yesterday I installed Ubuntu studio (and already I can't wait to uninstall, and go back to Debian, but that's another story
and for fun I checked out the shipped Oolite (1.77)
... And I just... what? huh?
The ole Cobra was tilting and drifting in a most peculiar way...
Then it hit me: I was running it on an old macbook, and it took input from how the laptop was oriented, there seemed to be some tiltsensors active.
Kinda neat, I guess, I could in theory steer by wildly flailing around the laptop, like I'm doing Wii sports, but frankly, it's a serious PITA because I don't see how to switch it off....
