That compass/ruler symbol is the mark of the free masons. I think all of those symbols are linked to the masons in one way or another. 5 stars for the combination of zooming and those noises for giving me a bit of anxiety
The NWO secretly killed John Cage, and put his brain in a jar. It sits on a desk and provides moody soundscapes to opress people by. One day the brain juices will pickle, and they will replace it with Brian Eno.
Apparently the sounds are made by a program called audiopaint, it reads pictures files and creates sounds from them. This is actually pretty damn neat, I'm downloading it now.
You can download the program for free here
