BlinkM - I2C Controlled Programmable RGB LEDs.
BlinkMs are Programmable! With ThingMs sequencer software, you can create
a mix of colors with different time slices, upload that sequence to the Blink, and then let it rip.
They also have the BlinkM MaxM - I2C Controlled RGB LEDs.
MaxM Master runs our unique firmware that creates virtually any RGB color,
fades smoothly between two colors, and blinks in virtually any pattern.
Not sure if these are what you need or not. That is the best I could find.
