I've written my first Movable Type plugin: MTMaps. It basically makes it a lot easier to build the kind of photo/blog/map mashup that I've been playing around with lately.

I'm now using it to generate the map for my photojournal of San Francisco. (Which I haven't updated lately because I've been busy re-learning Perl for the 3rd time in order to write this plugin...)

If anyone out there is an MT user and would like to download MTMaps and kick the tires, I'd be much obliged.
