A Magic Device called an "Air Harp".. Aka a Ultrasonic Distance Sensor strapped to an Arduino UNO with code.
Works as a MIDI player in Garage Band. So wave your hand push some buttons and let the magic begin...

It still uses Peter Alaric DeSimone code but I am unsure "Harp" would be a good name for this while it looks like a Organ now...
This is the greatest thing to play with ever....
