There's something about test patterns and calibration screens that fascinates me. I'd like to make a documentary looking at test-patterns through history and their purpose and call it 'Please Adjust Your Set: A History of Test Patterns'.

If I could have recorded this stuff, I totally would have. I mean, how rare is dead air on it's own? And all of this other stuff? For over half an hour!? I told my wife that this is the tele-visual equivalent of Halley's Comet, but perhaps that's stretching it a bit too far.
