Show HN: Geoground, get a map image based on user's IP (jarqu.es)

I recently started working on a small app that I wanted to look slightly personalized per user by showing a faded image of their city as a background.

I couldn't find a service that did this for me, so I made a stupidly simple one. Simply use http://g.jarqu.es/IP and it'll return an image of the city based on the IP address.

It shows me a blue field. Since it's not possible to zoom out, I cannot see which lake or sea it is.
