A trio of tools for Google Maps hacking: the Unofficial Google Maps Embedding How-To seems to supercede the GMaps-Standalone hack I linked to earlier (via Google Maps Mania); Noah’s Google Maps Hack for Large Maps allows you to make poster-sized maps from Google Maps tiles (thanks Noah); and gMapTrack, which seems to be a site for creating your own custom maps without the DIY hackery (via Google Maps Mania).
