I hacked together this little ruby script to read the G-measuring device in the Thinkpad’s harddisk (HDAPS) and rotate the desktop cube of Beryl when sudden movement occurs. A bit like what has been done for the MacBook already.

GPL, obviously. It’s not really perfect yet. I’ll try to improve it tomorrow and add support for compiz and maybe even make a little widget out of it.
It’s based on code by Fer, which is for Compiz instead of Beryl.
