for my third iteration, i went minimalist. just 3 LEDs, facing directly upward towards the ceiling, to create a color mixture projection. finally got to implement PWM (pulse width modulation), so the LEDs can now fade on and off, allowing for this mixing of the colors.
ideally, Red Green and Blue would make WHITE, but the green is brighter than the rest. I need to add a resistor on that guy, and it should fix the problem. v04 will be completely different, however.
