I'm sure someone's thought of this before, but this was an experiment to create a gif animation for the first time: I wanted to see what the Eve Influence has done over time. Since this is my first shot, it's a large file and not very optimized.
Here's a gif animation of the maps from 10 Aug 07 - 24 Nov 07Eve Influence Map vs Time (6MB gif animation)

First time I've done a gif before, but it's pretty interesting to look at the map like this. Perhaps the same technique over a longer period using 1/2 month increments would be more illuminating.
