I've now got a webpage that lets you create your own heat maps! http://www.campusactivism.org/heatmap/heat.php
It produce tile layers for Google Maps. One for each zoom level. It combines them into a tar file that you can download to use on your own website. The system is slow. I've been using it for mapping the heat of around 100-1500 data points, creating tiles up to zoom level 7 or 8 for the entire lower 48 US states, and at a resolution of around 0.1 longitude by 0.08 latitude. That can take up to 40 minutes. You can get it to send you an email notification when the script is done (so long as it doesn't time out). It is dramatically faster if you don't need to zoom in so far. Each zoom level makes it 4 times slower. It would also be far faster if you did a smaller geographical area - like a single state. Speed is directly proportional to the longitude resolution * the latitude resolution.
