Playano is a device that project indicators onto a piano keyboard so that a begginer can play whatever they feel like.

The laser projector is MIDI compatible, takes USB input and should be easy to use with any music tools. We also have (experimental) software that can fetch any song from youtube and translate it into piano chords to display them for you. It's very experimental - don't expect it to work perfectly - and is quite challenging to install - requires Googles Magenta Platform, and was only tested on MacOS.
If you want to play with any of this, contact me - Marek Baczynski - at es.htk|abkeram#es.htk|abkeram or dm me on twitter: @markshouts
This wiki page will be extended if there is interest in using out prototype.
