Looping rotation?

Hello. I want to have an object rotate to a degree locally, and then rotate to another degree that is relative to that position (so if the first rotation was 180 and the second was -100, the object would end up facing 80 degrees from its first position) and then have it repeat.

I know how to make an object rotate, but how would I do the second rotation and then how would I have the whole thing loop?
