working on my own ideas re RIP chair. dont fancy tracks, think 6 wheeled arthropod, dual electric/IC drive. also re 'wrong trousers', lol, did anyone see the segement on Richard Hammond's program about exoskeletons? haven't seen it yet but kids thought it interesting. tried a self-propelled wheelchair yesterday, managed 10m down corridor before the engine (me) ran out of power! its a start tho.
