CommandophoneThis is a musical toy inspired by Andre Michelle's Pulsate.
Circles expand and contract and play notes when the bounce off each
other. My version incorporates a number of embellishments compared to
the original, including multiple voices, choice of instruments and key,
and the ability to move and delete circles.
The name was chosen because the graphics reminded me of the game Missile Commander.
To run it you will need Python 2.7, PyGame 1.9.1 and a MIDI output device (either real or virtual).
