I like the color bomb when you switch away from the tab for a bit and come back to an onslaught of events get processed by the UI.

Is this a side effect of how the browser handles canvas rendering or did it have to be explicitly coded?

Many browsers throttle javascript performance (particularly looping timers) when the tab doesn't have focus. My guess is the "color bomb" is just a side effect of the JS performance returning to a normal level when focus returns to the tab.
