The Science Museum in London has this incredible exhibit called Listening Post which displays random message from internet chat sites on a board of green text displays. At the same time some of the messages are read out, each one in a different tone. It's hypnotic. This is what it looks and sounds like, but really, you should go and see it. It's free too but it's only there until the 21st.
Here's my phone video:
The artists have their own, obviously much bettr videos here but you need to download them. Youtube has several more videos too. This one shows the "I am" section very well.
Some of the messages are silly "night night snuggle bunny", or trivial "there was a mouse, terissa" but lots are discussing Afghanistan and some are quite chilling "kill the jews".
