There are plenty of "light movers" out there.. Pot heads..oops I mean gardeners have been using them for years..

However a light mover is NOT to simulate the sun. Its to reduce the amount of light fixtures required to cover a certain area.
Sunrise/sunset/slope dimming are all possible now with just about all the reef controllers out there. Dimmable LED drivers simply accept a 10V PWM or 1-10V analog or even 100K potentiometer for dimming. Heck some "geeks" are even doing lightning/cloud/storm effects via simple dimming of the LED driver.
Done with the arduino already too.
