Once upon a time there was a website called stickdeath.com where a certain demented animator had animations of stickmen in dire predicaments.
Well, he had one intro animation showing Stephen Hawking on a turbo charged chair, he then peeled out and off a stunt ramp.
I did save the animation to my machine.
Can you post it?
He just had his 70th birthday and I read an article about him which included an interview.
Probably connect to your ramp stunt, Hawking said he used to love to crach his chair to freak people out.
