Parametric-controlled motion or timing

Learning Solidworks, I am attempting to create an animation of mirror reflections in a sketch (see attached; also http://zawala.com/mirror_study.sldprt).

Editing the sketch, I change the encircled angle value which provides an optimized spatial relationship of two mirrors. I would like to animate this view, using the circled angle parametric as my driver or "stepper" for my motion study. I would like to increment this value, say 1° every second (or 8 frames).

Can this be done in Solidworks? If so, how?

Thanks a bunch.
