Sound and moon

My blog appears to be just about dead, but I'm keeping it hanging on every once in a while. I'd like to post more, but college and work are keeping me really busy.

Anyway, just ran across this, and thought it was a pretty good demonstration of a speaker for those curious.

Also, combo post! Here's a photo I took of the moon eclipse a while back.
