Zoki64, the creator of this beauty, calls it the "Finger Print Magnet64" -- and I'm sure it's obvious why. This thing is so glossy that you probably smudge it just by looking at it!
I'm not even sure I'd want to actually use this controller. It's too pretty, but that shouldn't be a surprise: Zoki64's work is often gorgeous.
