Here’s a interesting Google Maps Mashup I created which maps out your twitter followers. The map animates thru 100 followers at a time. The information window at the location also shows the latest tweet by your Twitter follower. There is a previous and next buttons at the top which retrieves info on previous/next 100 followers. The url of this mashup is:
