Thanks that was a fun one to work on! I initially had it working at the second level HH:MM:SS but the zooming in and out on the canvas every second gave people whiplash.

I wonder if you could find all the seconds in the region around the HH:MM time — or more to the point, how much do you need to zoom out to find the nearest SS pair?

Then you could keep the HH:MM time centered as it is now, but highlight the nearest SS each second.

		That's a good idea! It would make that sixty seconds a little bit more engaging instead of just hanging around on one time and having to wait before it zooms out to find the next HH:MM combination. I had initially set it up to go for each second, but it was physically giving me whiplash.
