sunrise/sunset timer?

Does anyone know of an affordable or DIY led sunrise/sunset controller? (aka use pwm to slowly turn up the lights over a 20 min ish period and revers for the evening?)

It would be nice to have it a little more natural for the fish and i'm guessing it would help spawning cycles aswell.
