To be honest with you there, Tape, that's a pretty tall order. I'm pretty good with photoshop, but "warcraft" would have to be completely wiped away, and you'd be left with a blank spot so you'd then have to completely re-create the grid background, complete with the shading a texture.
Then, if you can get it to look half decent, then you have to be able to recreate that font, which looks to be quite a difficult task, unless you have the warcraft true type font loaded on your PC.
I'd like to try, but I couldn't even attempt to try it. I know it would look stupid when I'd be through with it. If someone here can do it and post it here, I would love to see it.
