The new version of Chairgun for iPhone (possibly Android too, I'm not sure) uses the camera and the built in accelerometer. If it has your usual setup programmed in, just point the camera at the target and the app tells you the angle and your changed aimpoints. Very clever, though I've not tried this in practice yet.
