Virtually everyone will want to watch Prisoners Of Gravity this week for a reality check on virtual reality. Commander Rick gets the low down from Larry Niven and Steven Barnes (co-authors of the Dream Park series), Douglas Adams (The Hitchhiker's Guide To The Galaxy), Neal Stephenson (Snowcrash), William Gibson (Neuromancer), Greg Bear (Moving Mars), James Patrick Kelly ("Mr. Boy"). Rick also talks with nonfiction writers Donald A. Norman (Things That Make Us Smart) and Bill McKibben (The Age Of Missing Information) and virtual reality pioneer and guru Jaron Lanier.
