Google Maps Astronomy Mashups?

Mike Pegg notes that despite the fact that it’s been a few months since the Google Maps API supported Moon, Mars and Sky, “we have not been inundated with Google Maps mash-ups that have taken advantage of these new astronomical features.” He gives some examples. As for me, I can see the utility of using the space tiles as a way to log one’s astronomical observations or astrophotography; things will get interesting when My Maps support is added. (It hasn’t already been added and I’ve missed it, right?)
