It's 8 bit linear, your eyes are logarithmic, if the controller was 8 bit sRGB then it would be good enough, but 8 bit linear doesn't have enough resolution in the low range, which is noticeable in a slow fade to black.

@pike: 8 bit per color. Makes 24 bit full color, which is decent.

The boblight add-on for XBMC captures 32x32 pixel video frames.
illiac4 Wrote:I would say go with adalight and boblight if you are on linux. I have already buld two one based on amblone but with boblight and other with ws2801 led stripe and boblight. For the first one i have written tutorial under linux section on this forum, for other based on adalight take a look at http://stmlabs.com/forum/topic/tutorial-...nd-arduino
If you are going to build the one on ws2801 stripe just go with arduino Duemilanove because you do not need pwm outputs. If you are going to build four channel rgb stripe based one than go with mega.

They shift virtually at the same time.
You will never see a difference between the first and the last LED providing they show the same color that is
I would not worry to much. Get a UNO board and 2 x 25 LED from adafruit.com.
I can really recommend this setup.

Thanks
