Earthquake Heatmap

It would be better to repeat the data at both sides of the 180 meridian. I was almost going to ask: What is the big isolated red spot at the east of New Zealand?

(Does Hawaii have it's own real red spot?)

More feature request:

I'd also like a standard play/pause/first/last buttons. Bonus points if the buttons disappear when the mouse doesn't move.

I'd like another "mode", where the old quakes don't accumulate. The old one just disappear. Or they turn brown, then light brown and then disappear. It will be necessary to tweak the visual representation until it looks nice.
