I wrote a video synthesizer based on the idea behind cha/ves, but used an Arduino to generate the oscillator waves that control the VGA pins. I used an Arduino Uno that was laying around. It ended up spending most of the time just reading the MIDI data. It could do about 10 "pixels" per screen refresh. It was neat to see how slow the code I wrote was though, if I accidentally added a modulo or divide operation I would get half as many pixels onto the screen. Too bad the Arduino standard library uses % for serial buffer checking, random, and other features.. it made some cool glitches but was just too slow. Moving on to a raspberry pi and working through the book of shaders now.
