This extremely extreme wheelchair mixes two very distinct, yet not disharmonious, aesthetics: tank treads and, what appears to be, the most comfortable seating apparatus modern science can come up with. This isn't the first TankChair – that one came out in 2006 – but the newer TankChair has made some notable improvements, including a lower center of gravity, more torque, a stronger chassis, and the aforementioned comfy seat. We're not sure about the cost or availability but, for the right person, we can imagine the new TankChair being a godsend for the rural handicapped.

The students on the Palo Alto High School InvenTeam arrived at the Stanford Cool Products Expo this year with a new system designed to allow quadriplegics to operate all kinds of gadgets and appliances. The user shakes his head to activate a glasses-mounted laser, which he can then point at sensors embedded in an array of custom triggers placed around the home. So far the team's nailed the basic on/off circuit needed for lights, fans, and a pet food dispenser (which is currently shelling out M&M's to Expo attendees), but the real noise is their plan to extend the system by building a small robot that will perform various tasks. According to the school, team captain Guy Davidson was only kidding a little when he said the team hoped "to have [the user] vacuuming in a few weeks." While this isn't the first time we've seen lasers used to assist the disabled, you gotta wonder what's going to happen to their altruisitic spirit when these kids realize they can also just headmount one of those crazy high-powered laser pointers.

Looking to expand the moviegoing experience as much as possible -- especially in this day and age of 103-inch plasmas -- a research team at the University Carlos III of Madrid has unveiled an upgrade for the problematic rear-window captioning system currently used by the deaf: a glasses-mounted subtitle screen. Featuring a three hour battery life and a 50 meter range, the little clippy-screen isn't as hard-core as some other enhanced vision devices we've seen, but there's something to be said for doing one job well. That range is pretty long though - no word yet on how the MPAA plans to deal with people sitting outside the the theater and reading the latest flicks for free.
