He's also in the CC credits.

Edit: See here. This also includes Edwin Bakker for "Additional Art". That refers to the splash screen I suppose, as it seems to be in neither Nick's or Noogy's style, and CC99 is a Project 2 project if I recall correctly - which would match Edwin Bakker's Dutch name.

It also has a bunch of people who made the user levels included with CC99. Hey there, FQuist!

Edit 2: I vaguely recall some kind of connection between Noogy and Scotty Cone. No idea about the specifics, and I might be thinking of something else...
