Hello!
I wanted to announce a new open source firmware project that uses the Teensy 3.0 to control WS2811/WS2812 LED strips. This one builds on OctoWS2811, adding an interpolation and dithering engine that lets it do much smoother colors and fades than you'd get otherwise. Some quick stats:
https://github.com/scanlime/fadecandy
Hope some of you find this useful. The temporal dithering algorithm is something I've been excited to use, since it finally opens up the door for subtle effects that look good over a wide range of brightnesses. It's hard to convey the difference in video or photos, but if you have a Teensy that's already set up for OctoWS2811, I'd encourage you to give this project a try.
Thanks!

- 512 LED pixels per Teensy board
- 395 FPS hardware refresh rate
- Temporal dithering algorithm, for 48-bit color
- Color correction and gamma in firmware
- Efficient USB protocol
- Smooth interpolation between keyframes
- Open Pixel Control server for Linux & Mac, including Raspberry Pi
