Your hearing this here first, I think.
I just got word that there will be a 8MM domed RGB LED with a built in WS2811 IC. This will be just like the 5050 with the built in WS2811. I expect the price of pixel strings to come down soon once it's released.
The WS2811 snowfall tubes that I'm working on my go color now.
Can you say "COOL"
