This web app is mainly targeted at people playing with a MaKeyMaKey - see http://makeymakey.com/ - and maps certain keys to piano sounds. The keys space, left, up, right, down, w, a, s are mapped to C major pitches. This app is running on http://piano.kairo.at/ The main repo is http://git-public.kairo.at/?p=makeypiano.git;a=summary but it's listed on GitHub at https://github.com/KaiRo-at/makeypiano for convenience for potential contributors. See the TODO for tasks that you can help with. Please don't use GitHub for issue tracking but http://bugzilla.kairo.at/
