These come from Digital Dreams: The Work of the Sony Design Center, by Paul Kunkel, the guy who wrote AppleDesign, a book I’m still kicking myself for not buying when I had the chance.
This is the joint Nintendo/Sony unit from 1998 – as a compromise with Nintendo, it had a cartridge slot as well as a CD-ROM drive.
They went through two dozen controler concepts. Sorry about the lousy scan.
My favorite, the logo iterations.
Maybe someday a design study will surface for the PS2.
I write screenplays, books and push software; I'm a collector and indoorsman. If you have a Masonic scepter or a copy of the Boyd Philadelphia Blue Book (any year), drop me a line.
