I like the stop button idea, but there are some considerations that I need to work through before I can add it in.

the intention behind using the url hash for application state is to allow sections to be debugged and sent as links. that said, I may rip it out in place of a smooth zoom when I get time.

Looking at it moving for more than 3 seconds made me quite nauseous if I zoomed in.

You could adjust the URL hash without pushing the change onto the history stack -- that gets you the best of both worlds.

Looks like this has been implemented now, but I can't find any way to zoom back out!
