English artist David Shrigley is known best for crude, child-like drawings used to illustrate and comment on the absurdities of life. He's got a new exhibition on at the Yerba Buena Center for the Arts called "Brain Activity" which just opened over the weekend and will be open through September 23. Watch this charming video of Shrigley at work, spontaneously drawing an elephant. With spectacles.

TimeOut London says of him,"David Shrigley's art operates at the cross-roads of art, absurdity and philosophy…It's like Kierkegaard, only with marker pens, poster paint and crappily-made sculpture." See more of Shrigley talking about his work below.
