I saw this on the News Hour last night:

Whirlwind Rough Rider. Designed to be cheap to build, servicable anywhere in the world and tough. I think it also looks better than traditional wheelchairs.

Pretty cool chair. It has super wide front casters for getting through all sorts of terrain. Works great on dirt and mud!
