You're probably right Art. That is the real gif he has posted though. I had thought about the Hal character, it is stretched out lips and he could mask over the "TV" set. I have one or two more wave .gifs he may be interested in. I think Duskrider explained the concept best. A Windows media player window. How could you route hal's voice through the media player and how could you show a live window inside the user interface? Faking it may be even tougher. The timing would give the illusion away.
