Time lapse gismo

Although I have some idea how to use several stepper motors to make this thing work, but have no idea about electronic boards or software that would control 3 motors (most times simultaneously). Any suggestions where to start would be helpful.

If you have some ideas, then why not share them? It's impossible to guess what you are trying to do, other than it has something to do with time lapse.
