That's very cool. I appreciate the mod. :)
I'm seeing something that looks like a bug (in both versions)... but I'm 
not sure if the accelerometers require calibration or something.
With the FR in vertical position, if I tilt it counter-clockwise, it 
takes just over 90 degrees to get 'accel-rotate' to change the 
orientation; but if I tilt it even less than 10 degrees clockwise after 
that, it reverts back to the original orientation.
Shouldn't the threshold be set at the midpoint angles (45, 135, 225, 315 
Anyway, good work to both coders, it's just what I wanted. :D
Maybe someone cares to extend this simple app to use some kind of sexy 
morph instead of the disruptive xrandr rotation? 8-)
