It's not on TV anymore but that test pattern used to scare me to death. Just thinking about it gives me the creeps.
I use to fall asleep babysitting and would have to walk to the TV with my eyes and ears closed to turn it off. For young people it was this awful picture of circles and lines with a terrible buzzing after the TV went off the air for the night.
I forgot the movie but there was a movie on where people were watching TV and it showed it and even on a small screen on TV it made me close my eyes.
Weird, huh???
