I mentioned the MGM/Disney Studios theme park ride the "Rockin Roller Coaster" and that it was designed in AutoCAD by David Harrington.
If you attended AU 2005 you may have rode the ride but now you can see the DWF sheet of the huge guitar at the entrance where the strings run into the ride building and give the appearance of becoming roller coaster tracks.
