Debut: A New Mind-Controlled Bionic Limb

"Skyrise Chicago" debuts a new, thought-controlled prosthetic leg from the Rehabilitation Institute of Chicago to climb Chicago’s Willis Tower (still commonly referred to as the Sears Tower) in less than an hour - Update: Senator Mark Kirk didn't climb all 103 floors Sunday, but started on the building's 66th floor and climbed to the 103rd floor.
