Yea I have seen the ones at MojoArts. I have actually been using pieces of the Monkey Island 2 box they have scanned there with a scan of my own. I don't know, I guess I just enjoy the logos on it, probably because that's what I have seen my entire life.
Within time I will make one and let everyone know how it comes out and if I ran into any problems with the LucasArts logo. A few of the images on the first page of this thread (Indiana Jones and the Day of the Tentacle) have the LucasArts logo on them, so we'll just see what happens I suppose!
