It is very useful right now if you want to control 1 axis of a machine. You can use it to remotely move an OSSM/ Handy in real-time, record 1 axis scripts on the fly, and other things. The only multiaxis toys that I know of are the strokers from Tempest. However, I am going to add the IMU to this once I finish some other things that I am more interested in at the moment.
