You sometimes see video of a nuclear blast; but the first frames just show a ball of plasma that looks like an opaque white cloud. The light from the blast washes out everything else; there's no sense of scale. Is that 100 feet across, or a mile across? And how long ago was the blast?
Slo-mo video, with a size scale and a clock, would be fascinating. But a sequence of rapatronic stills would be very interesting.
