I've said it before but I'd love to see a Radiohead pin but designed in conjunction with the band to create all new music and sounds and artwork. It would be very abstract and reactive like Rez the computer game, the music and SFX would change depending on your shots and progression. Also, assuming I could get Radiohead on board, the publicity of a pinball machine being their 'new album' would be great for pinball.
It wouldn't be sad Radiohead like High and Dry it would be electronic, industrial, and funky like King of Limbs.
It wouldn't even have to be Radiohead but getting some similar musicians to do an abstract table like I described would be my perfect pin... in theory.
Well, you did ask...
