A few months back I attended an Unlimited Potential event on design and technology. A prototype of the NASA research based "Zero-Gee" chair - a 135° zero-gravity motorized ergonomic chair - made its appearance and got some interesting reactions from the audience. Well, its gone from design to prototype to reality. I had an email last week from Tom Rynaarts letting me know the first small batch is close to delivery. Talk about a great concept, bound to be a strong following in tech communities for this ultimate piece of hardware. Now, where did I put that spare Xmas money!
PS. Unfortunately they're not generally available yet, but keep an eye out ;-)
