I was standing around Ironforge tonight, about to log out of World of Warcraft, when gnomes started falling from the sky.
"Huh, that's never happened before", I thought.
As it happens, the gnomes were falling in a very particular pattern, and when they landed they died, leaving their bodies on the ground in pre-determined spots. Someone decided to do some very clever advertising, see the screenshot, below:
I took several screenshots inside WoW, and then put them together quite easily using the free, open source program "Hugin". It was pretty easy to use, I recommend it for photo joining (aka stitching).
