One of the best things about the original Starcraft was the Map Editor. With this program, you could design not only your own multiplayer levels, but entire story arcs if you so chose. With Starcraft 2 out for about a week now, it was only a matter of time before some people started to work on some nifty ideas. The video above is easily one of the geekiest things I can imagine.
