DKWatson:
If you want 'cylon' lighting, you need to turn each LED off before you turn the next one on.
Repectfully disagree artistically speaking for vintage cyclon eyes.
Should have 5 LEDs lit at all times , Center full brightness, inner left/right 66% brightness, and outer left/right at 33%. You move the brightness levels. Once a 33% LED hits a side, you trigger counter backwards so that it spends 2 cycles on the same spot.
A diffusion screen innfront of the LEDs would help also..
