Awesome video from a talk at the 33c3 by Joscha Bach:
It's about the universe, digital physics, life, the world as a dream produced by our perception, a synthesizer model of cognition, the conductor theory of our consciosness, the value of entropy, altruism versus selfishness and so forth. A complete new perspecive on the meaning of life or the lack thereof.
Makes your head explode if you think carefully about it.
