Confirm Info Animation

I'm starting to experience with more exciting submit button animations. The average user is beginning to expect a reaction when a button is pressed and the subtle color change that used to be enough often doesn't work as well. This often results in people pressing the submit button repeatedly, not confident in its working, which is a heuristic failure!
Although this may be more fun than function, the idea of a submit button that changes in a dramatic fashion is going to become increasingly normal.
