Red, White, and Blue tapestry
Software: This is FastLED’s built-in simplex noise + built-in palette support + the XY example code + the RedWhiteAndBlue sample palette! Not much ‘sketch’ code here at all… I’ll try to post it later today, Arthur permitting.
Hardware is a loose matrix (about 6 feet wide by 5 feet high) of 200 WS2811 pixel nodes, diffused through a layer of organza and a cheap shower curtain with an interesting light-breaking pattern to it.
Controller is an Arduino Leonardo clone.
