I wouldn’t keep posting these Google Map hacks if they didn’t keep getting so darn awesome. The ability to customize Google Maps has been around for a few months now. But it has typically involved things like sending requests to various servers via Python proxies and altering XSL stylesheets (i.e. not for the faint of geek).
