Anthropology

square waves, Lissajous patterns and triangle oscilloscope waves and TV test patterns they've documented......

Just kidding of course but I am amazed at the precision of their drawings and would like to learn more about their techniques and the meanings of the symbols.

Let's hope the archaeologists thoroughly document this wonderful site before allowing the public in. Perhaps the government can block off and isolate some sections for preservation.

Thanks for posting, Judi Lynn!......
