John,
Of course ! BBC2 iplayer only available in UK. Programme in question was a learned treatise ("Chaos") on Ancient Egypt. Carved on a block of stone in a wall was a line of skeletal famine victims. For a period of some 15 seconds some (but not all) of these starting moving on the stone. Lecturer carried on, oblivious to this.
(2226 GMT 15 Jan) They're still at it !
Danny.
