I recently picked up a P5 Glove for a very decent $20, with the intention of creating a BB for Virtools experiments. It didn't take me that long to do, and the end result exposes all the available variables: position, absolute/relative yaw/pitch/roll, and the independant finger bend information. I haven't done anything too interesting just yet, but the Virtools P5 DLL and sample test are available for any interested parties (be warned--I have no idea what this does on systems that don't have the P5 driver installed).
