Ironically, cam...although your method sounds absurd and ridiculous, that's the exact method they used to film the bullet-time effects in the Matrix films. (Well...they didn't use thousands of cameras, but hundreds).
Would be insane if they built a massive 1000-camera rig around some place notorious for being struck by lightning (a lightning rod or something)...and managed to capture a bolt striking...then we could take the footage and pan around it and such, while the bolt is frozen midair
