Watching the earth rotate

I’ve always been fascinated with time lapse photography of stars.  And here’s one:

Watching the stars rotate is interesting but it’s not the stars that are rotating.  It’s earth.

That’s why I like this video with a camera rotating to compensate for the earth’s rotation.  The stars remain where they are (as it should be) and it’s earth you’ll see rotating.
