This is a message that Prin sent to the list that went all weird. I asked him to send it to me. I am now sending it to the list to see if it gets weird again... Regards Craig [original with line breaks] This-is-the-message-,again-plaintext Fingers-crossed-for the =20%'s Jeroen and I have discussed this before between us. We have an aged LCD TFT panel in the lab. A circular zone plate who's phase is changing at a critical speed gives a STATIC residual pattern of the zone plate when the source is removed. If you then do the classic waving of your fingers in front of your eyes you apparently see interlace twitter - the TFT panel was being driven with a progressive image. This is the effect of the combination of the two effects that Jeroen desribes.
