The Google Maps API now has a Flash version, alongside its regular JavaScript and static versions. On the Google Maps API blog, Mike Jones writes:

So, what do I like about the API for Flash? Smoothness and speed are a big part of it. We’ve designed it so that Flash graphics can be used for each tile layer, marker and info window — opening up possibilities like dynamic shading, shadowing, animation, and video. When the user zooms the map, magnification changes happen smoothly and place names fade in. After the user drags a marker, it gently bounces to a halt. Generally, Flash allows for much greater embellishment, and, well … “flashiness.” I get excited just thinking about the creative ways developers might take advantage of having a Flash API for Google Maps.
