Last night I released OctoWS2811 ... after spending pretty much all Sunday making this 3 minute video:
Everyone at the meetup a couple weeks ago saw this right when it was first showing video. Since then, pretty much all the work has been on the documentation and minor code improvements.
Just curious what "gamma" setting you use for your LED display. It's hard to tell from a video or still frame, but I'm wondering if you have it adjusted to give the most realistic (accurate?) image. If you show an exposure wedge, a set of evenly spaced gray tones from full black to full white, do the grays around 50% look like you would expect? The video suggests the mid-tones may be a bit bright, but that might be due to the video camera instead of the display.
