From time to time. I spend an afternoon doing some monographic research of a great Computer Scientist, or simply people I've seen some day in TED, and would like to know more about him/her.
Sometimes it's Joe Armstrong, sometimes it's Guy Steele, but Alan Kay and friends take these afternoons more often than others.
Here are 3 Conferences by Alan Kay and one from Dan Ingalls. Those two men (and their collegues at Xerox PARC) have done probably more for our field than any other single group in the 70 years of history of CS (or call it tinkering, or computer tekne)
Alan Kay at TED talk, sharing his ideas about ideas. 2007
If you liked it (you SHOULD like it), here you can see a longer talk about Alan's last work (STEPS)
Here's Dan Ingalls talking about his work at PARC Place. Great stuff too.
