This is pretty fantastic! I was wondering if there was a way to spit the parameters out into the URL with each change, or some other method for the user to save/load a configuration.

If that was possible, people might be able to

1. Come back to the exact configuration
2. Share a map to allow others to tweak
3. Create a "save state" of sorts allowing for Undo actions (i.e. 'navigate back')
