Spielberg on the future of cinema: "Dude, I've already invented it"

I thought I saw it too, at once Buffalo State College. Ken Jacobs put on a live performance piece in a lecture hall. There were three or four rear projection screens, on one he projected a red/green projector of some sort, and at one point in the performance, with 3D glasses on in the audience, his son rode a tricycle in front of the projector, projected onto the rear projection screen, and a monstrous image of a tot on tricycle loomed out over the crowd. It was to commemorate the American composer Charles Ives, the Connecticut insurance businessman in "Lost Doll Found" Ironically while boiling his vinyl record in a 35mm film can, water splashed out and I thought we'd be electrocuted by the small record player found in most schools. There was a film festival in Buffalo, NY that summer (1974) trying to be the "Hollywood of the East" (former President Monroe is buried in the Hollywood Cemetery, Virginia, after being removed from the secular marble vaults across from the current Anthology Film Archives, in a former courthouse, near Second Ave, and Second Street in Manhattan, NYC which when it was being built also encountered a former cemetery thought moved.) So if Spielberg invented it, will the insurance industry cover it? I mean if someone sued for "Side Effects"? (nice book by Woody Allen).
