Does anyone know how the visual effects in the Dr. Who opening and
closing credits were done?  The early shows (Hartnell to middle
Pertwee) show a wavy pattern which looks like video feedback (what you
get if you point the camera into the monitor).  The psychedelic-tunnel
effect at the end of more recent shows is nice.  I have no guesses as
to how it was done.
