Just anothing thing I made in Garry's Mod. It's based off a little doodle I did, and similar experiences I've had in Team Fortress 2.
I don't know if this or my other GMod stuff could be considered wallpaper, but I tend to make these things to go on my desktop. I don't know why, but I think GMod pictures make great desktop wallpaper. If anyone can think of a better category for these things, let me know.
