This is to be a little hexmap you can draw scenarios on for table top gaming. I've not really done much with it, partly as I then found D&D was square based rather than hex. ;-)
Also the SVG structure I was starting with here I'm not too sure about, might be worthwhile to just use canvas instead and deal with more of the event mapping manually.
At one point, Open Hub analyzed source code for this project based on code location(s) available at that time. Since then, the code locations have been removed.
