Using a layer to create an animated counter

This has probably been asked before. Many times. But is it possible to create a layer with different images that cycles automatically giving a basic animation like an animated gif?

I really do not know. But what about a CP trait that calculates a number, adds one to it, etc. When it reaches a limit, it resets back to 1 and off it goes again. Use that number from the CP in a layer trait to display the level. However, I think you will need to slow down the CP otherwise everything might just flash between levels too quickly.
