Pushing it...

This scene contains twelve sprites animating location (plane and cloud,) angle of rotation (sun and moon) and opacity (pulsar, dimming of sky and dark overlay for the mountain.)

It also demonstrates interaction with the Lock Screen and the changing of the time scale to test animations spanning long periods of time.

Click on the 'pulsar' to speed up time itself! Watch a 24 hour cycle. Click again to get back to reality.

Wouldn't that make a nifty clock on your nightstand?
