Lots of laptops have accelerometers, now.
interesting. is this a yes/no system (move/still) or is there a measure?
a true accelerometer (3D) is not simple to do. a qicksilver switch is much simpler. I could imagine a metal ball (like a small mouse ball) surrounded with foam and coils around :-)
I know nothing about the accelerometers in laptops (I wonder if mine has one?), but true 3D accelerometers are made in quantities of millions for just a few dollars apiece. Solid-state MEMS (micro-electro-mechanical-systems) have come a long way in the last few years. They would provide the signals needed for both the zero-G detection and the games Randall mentioned.
