Saw this on Gizmodo. It is a stretcher concept, designed by Morten Wagener. The idea is to make it easy to transport patients down stairs using caterpillar tracks on the side bars. It appears to be a good, low-cost alternative to the segway-like gyro balanced solutions I have seen, like the ibot. An ambitious conceptual project and an "ID classic" but the color and the centerless wheels detract from the overall design.
