Like many others have said here, majority of the best designers I've personally had the pleasure of working with or encountering were all self-taught and had little to no formal design education. The few people I've known that did go to design school, weren't very good. Of course that's not to say that people who go to design school can't be extremely good. That's just personal observation from those I've work with (which isn't representative of designers everywhere).

Having said that, I've always been impressed with the Design School each time I've been there (don't actually know if its related to what you're looking for): http://dschool.stanford.edu/

Disclaimer: I am not a design major, my design skills are self-taught, and I'm a former Stanford student.
