Here is a quick setup I made to showcase the main features of my sprite animation package. The sprites I use for animation here are just numbers (0 to 9), but you can easily plug in your own sprites.

The top right shows the currently animated object's sprite.  The window on the left simply highlights that frame. The bottom right is a screenshot of what the animation looks like in the editor.
