Using Kinect and linux, we could have a sort of a musical keyboard to play!
First you'll need a kinect and an Ubuntu OS to run it.
Follow the instructions to install on install.sh and clone this repository. The code is on the folder below: cd OpenNI/Samples/kinectKeyboards
Too see it running just run the file: cd OpenNI/Platform/Linux/Bin/x64-Release ./Sample-kinectKeyboards
