Remind you of anything. This thing is really interesting! I'm reading about it in the book Designing Interactions by Bill Morridge. It's a fantastic book that I dip into from time to time.
If you didnt know Jeff went on in the future to drive innovations like the Palm Pda, Palm Os and Handspring Pdas. He is also a student of e human brain and has written a book called On intelligence that is an excellent read in itself.
