I Don't Care What You Say / Baby, Talk To Me

TED talks. They're great for just-graduated types. Keeps us sharp. Sharp like knives.

In this one, Evan Grant spends five minutes walking us through the basics of cymatics - the process of visualizing sound. Turns out, cymatics has been instrumental in researching dolphin language, and Grant has some interesting ideas about the relationship between sound-shapes and the natural world.
Plus, Grant acknowledges that these pictures make for beautiful art all on their own. (Check out the visualization of Beethoven's Ninth at about 3:00.)
