How do I do this?

So, you know how you can make something continuously move, even through blocks by doing this?

local part = script.Parent

while true do
	part.CFrame = part.CFrame * CFrame.new(0,1,0)
		wait(.01)
end

I wanted to know whether or not it was possible to make something keep rotating forever, using the CFrame.Angles. That way it would be rotating inside of a different block forever. If my question doesn't make sense, or it's not possible, just comment!

Thanks for the help!
