Google Maps API

Using the google maps api I made a map of all geocaches that I’ve found, centered on my home town. I’m pretty pleased with it so far. It requires the gpx of my finds uploaded to my webspace, the html page and a google maps api key.
I now have this at the top of my geocaching blog and would have it in this post if I could work out how to get an iframe to be displayed inline on a blog entry.
