On the more complicated front. Somebody was talking about a red/green/blue head for colour work.
I'm a complete dummy in electronics.

Hew uses very bright LED's. Is it possible to make individual LED's change light emission intensity (kind of rheostat)? With two pontiometers you would be in business.

Or do you have to switch on more or less LED's to get more or less blue/green? Then a greater amount of less light intensive LED's could simplify the contrast grades. You just switch on more or less blue and/or green LED's for different grades.

But maybe I'm talking bullsh...
