There's a webcomic called xkcd that is pretty popular among the comp-sci crowd. It bills itself as a comic of "romance, sarcasm, math and language" and it frequently makes jokes that reference obscure bits of programming knowledge.

Also, it's populated entirely by stick figures.

The above entry is entitled "GeoHashing", and it's pretty funny if you know what a hash function is (hint: the image above is an example of a hash function), and if you know what geo-caching is. And if I didn't work in the world of GPS, I'd have no idea.

A geocache is a box (typically) with stuff in it. It is located at a specific place and the GPS coordinates will be available on a website. You go the location, find the box, take something out, and put something else in. There's often a log book you can sign. I'm told it's great fun with the kids, and there are supposedly hundreds of these in the country.

Or, if you are less interested in finding things and more interested in seeing a place you've never been--try the function above. Who knows where you'll end up?
