Beautiful. I'll be using this API, stat. Using a transparent image overlay instead of divs really helps avoid overloading the browser, but it'd be nice if they'd load faster.

We look forward to seeing what you come up with!

Re: load times/image overlays/etc -- We hear you. I won't get into the nitty-gritty, but the backend engine is actually doing a lot of geoprocessing for each request (those images are all generated based on the latest data when requested -- no canned raster imagery), but we're constantly working to improve it, and subsequent releases should see substantial speed improvements and optimization.

However, a quick tip: If you're looking at it in IE v5.5 to anything less than 7, our overlays are transparent PNGs which requires loading a special hack through IE. We've noticed in our internal testing that this tends to make the images load a little slower in IE.

Enjoy!
