It is visualisation of simple technique to synchronise many clocks without central authority, algorithm is explained on left side of website. You need to turn on 'Nudge thy neighbour" and then wait for fireflies to sync.
Cool idea, but not applicable to our scenario. People would step in and there would be a 3-2-1 count and then step out. There was no flash to sync against. And even if there was, if the devices are all running at different speeds, the sync is moot.
