| Create a unit-sized image to divide up into the puzzle. The image cycles through four images upon toggleImage events. |
| Create the different images that will be used in the puzzle: |
| time-varying solid-colored image for background |
| image of time-varying elapsed time in seconds |
| first possible image for puzzle, time over colored background |
| second possibility, based on rendered geometry |
| third possibility, based in imported video |
| forth possibility, time in second over the video |
| Have these image behaviors run just once, so that they don't get restarted when events happen. |
| Cycle between the four images on occurence of this app event. |
