You are switching the layers instead of using show and hide. I added a quit button to stop the animation.
I tried this with both 16 milliseconds and 8 milliseconds. (I think 8 might be slightly better.) I still see some flicker though, even when I turn off the development tools. If it were fast enough I would just observe a solid purple rectangle. When I tried it as a standalone on a Mac it was even worse. What’s up with that! One would think it should be more efficient not less. Your thoughts?
