A few cool wheelchair ideas on youtube. check them out.
This is an omnidirectional wheelchair. The seat can face any direction while driving. Very cool, but looks like a slow chair. http://www.youtube.com/watch?v=hcHai06iNZY Another chair that goes any direction, but this is not just the seat, but the chair can drive sideways. Looks 4x4 off-road too. http://www.youtube.com/watch?v=VpdRhi2ruoU Cool hands free wheelchair bowling. Except placing the ball on. http://www.youtube.com/watch?v=Y4i6DaLYmic Slide the seat you are sitting on, right into the car seat. (manual chair) http://www.youtube.com/watch?v=J24HfIMUIPc Greg
