Vi Hart's Twelve Tones

If anyone could give the question to the answer to life, the universe and everything, it's Vi. In intertube standards this video is long at 30 minutes, but I assure you it's well worth the time. This is a thing of beauty and intelligence. Also, "the harsh vacuum of space punctuated with giant balls of nuclear explosion times." http://youtu.be/4niz8TfY794
