Just a simple quick wallpaper that I did to Portal.
Just technically got bored and created this.
Hope it turned out okay.
EDIT: Goddammit, someone mentioned that it's identical to a t-shirt design, and I'm terribly sorry for that. I swear I had no idea, I confess that all this is a huge misunderstanding and accident. Again, I'm sorry for this coincidence, but I simply had no idea. I hope this isn't fraud or anything, and if anything, I'm saying this right now that I'm not claiming rights on any of this, and this is pure coincidence and accident. All these things belong to Valve and is from the Portal series, and the t-shirt design that the person sent me comes from Jinx. I hope I've cleared some things out if anything...
