Moving sculpture by Barry McGee bangs its head into wall over and over

Sometimes, I feel just like this sculpture by Barry McGee. Shown at the Perrotin Gallery in Los Angeles, this sculpture of a wooden head has but one hobby: to bang it's head into the wall over and over on an endless loop. If you look closely, you'll even see a scuff on the wall from the impact. I want to give the stressed out statue a hug and a cup of chamomile tea!
