Holy good god, it's been how long? Thinking about design, i'm always inspired by what is obvious/not obvious. I have a wheel chair. I use it to haul stuff. Today, i modified it. The potential of a machine capable of easily handling 350 lbs of flesh, stands up and does a split with 50 lb. It laughs at the challenge. Other advantages are: turning radius. Width(doors!). Light Weight. Strong. Looks Weird. Aoxomoxoa~!~ Meanwhile, the challenge and struggle continue!
