Never had an aspiration to build something yourself? I wanted to build something like a solotrek or an early version springtail... I have an engineering degree, I understand physics, what makes this such an insurmountable task? Now as for Martin/Zimmerman, I think we've all speculated about as much as possible, let it go to court, let the facts come out, let the jury decide if he's guilty, and let the judge sentence him if required... There isn't much else to say.
