Up, not North – Introducing The Pianocade: an Open Source Chiptunes Synthesizer. Jon writes -

It’s been a long time coming, but I can finally unveil the product I’ve been working on for months: the Pianocade, my first foray into the world of commercial Making! Inspired by my experience working on the Nuit Blanche Chiptunes concert last fall, the Pianocade is a programmable synthesizer and MIDI controller made to look, feel, and sound like vintage arcade games.
