Nice. I really like the color blending part! Thanks for posting the code to that. I'm going to (try to) integrate that into my NeoPixel GPS Clock. That is, if I can clear up enough memory and get timing right! It was tricky enough to get the GPS Shield AND NeoPixels to work at the same time.

how if i want to connect to the RTC, how should I input the code?

how do you connect the power supply yo the arduino and then to the LEDs?

hey, i've uploaded your sketch as well as goggles. Goggles worked fine for about a minute but now only 1 LED is working, and just in green. Any ideas whats happened? I have wired the neopixel up to the uno, 3 wires, no resistors or capacitors. Is that the problem? I feel that it is fried? Your help would be very welcome! Thanks

Could the code be easily altered to a 24 hour clock if a 24 pixel ring was used?

I like the clock idea. I'm not sure how to divide the 16 pixels into 12 hours though. Maybe 12, 3, 6 and 9 should have two pixels each?
I have three of these rings and tried to make some "hypno" looking patterns with them. Will YT let me post a link here? WS2812HypnoRings130823a
Cool, they did.
The Propeller lets you use one cog to continuously update the LEDs in the background while the other cog takes care of moving the pattern around.
Thanks for posting your video.

Everything's going anticlockwise... :/

I wonder how big each library is, it would be nice to pair them down to essential functions. (especially since neopixel uses AdaGFX and AdaNeoPixel).

I just learned about code.google.com/p/fastspi which can drive these without the adafruit libraries as well.
