One more I've been working on: My wife and I have been watching Star Trek TNG together(my 4th time or so), her first. I though it would be cool to follow the path that the enterprise took, and couldn't find a good site that did so dynamically.

I've been pulling a bunch of stuff from Memory Alpha, Scripts, and the Star Charts, and have a reasonably interesting visualization of a few series.

A lot of the locations are inferred due to... storytelling.
