Here's a quick and simple C program that reads a packet from the
accelerometer once per second, and rotates the screen to a new
orientation if the orientation has changed.
I don't mean this to conflict with Paul's excellent work on Gestures; my reason for writing it is so that it can be used as an always-on daemon in the OM distributions. (Full gesture interpretation is more CPU heavy and requires reading data more often than once per second, so perhaps that will be done on-demand instead of always-on.)
The code is: http://github.com/cjb/freerunner-rotate/tree/master/rotate.c?raw=true
