Earlier, I made a vvvv module for FingerplayMIDI, the Android MIDI controller app. Fingerplay is great fun, but I wished it had support for the Android Sensor API. After the source code was released, myself and visy decided to have a go.
Here is the result (hosted on Github for the time being). I also updated the vvvv module. Note that Fingerplay now support custom layouts. This module was built only with the default layout in mind (I don't know if there is currently a way to find out about the current layout on the server side...).
