This thread [0] from couple of days back on Alan Kay's views on recreating Xerox PARC seems relevant.
I think Google managed to recreate something similar with their 20% projects
Other companies have had the 15% / 20% culture, etc. long before Google. Example, http://archive.wired.com/techbiz/media/news/1998/01/9858
Sam, when I met you at Startup School last year, I wanted to be brief. The most important thing I wanted to communicate to you was my gratitude, and I thanked you for sharing your startup class. I'm blown away by and so grateful for the stuff you've been doing since. I'm very excited to see how these new projects work out. Thank you again man.
