years ago i saw something similar on a german "science" tv show. they build a barrel like contraption with 8 rows of 128 led's across lengthwise which was then spun up to about 2000 rpm.
i felt unsafe just watching on tv, in the studio everone shrunk away from the thing.
they then connected a tv reciever and voila, a mechanical tv set. pretty good picture considering...
no reference on the net that i could find....
