How to spin a circle on it's axis?

I’ve seen this done before and I still can’t figure out how to do it.
It’s a circle standing still spinning on it’s own center axis.
Preloaders sometimes show it.

I’ve seen the circular movement tutorial here on kirupa, and that isn’t it.

Like this game does…
Sorry for the crappy example, and site! I’m sure there are much better ones out there.
