Another favorite: Doors of Perception.

If I ever have thousands of dollars to throw around on my own intellectual pursuits, I'm getting a front row seat to a Doors of Perception conference in Europe. A conference chock full of designers, artists, architects, musicians -- whatever strikes their fancy -- all talking about how design and culture fit together...

Doors is a conference, website, knowledge network, and cultural accelerator. We bring together innovators, entrepreneurs, educators, and designers who want to imagine alternative futures - sustainable ones - and take design steps to realize them.

Yes, it sounds like a bunch of wank, but if you look at their site, you'll realize this isn't a bunch of artsy rhetoric. (The site is ugly as hell, but mind-bogglingly full of fascinating stuff.)
