Kitchen lighting perfboard prototype

It's got 16 5chip 1/2 LEDs. Most of them are cool-white now. Initially it had 50%/50% cool/warm-white, but the warm-white ones have died prematurely - for unknown reason. This one still uses an ATtiny2313 as the brain, but I think I'll switch to a Mega48/88 later. It's got a real SPI unit, which can send out the data much quicker than the 2313's USI unit. This is crucial, as the PWM interrupt must finish very quickly for proper performance.
