Below is a beautiful variation of an accidental performance I saw in the lobby of the Westin at TED 2009, where Eric Lewis played piano and Xtracycle Founder and Inventor Ross Evans jumped through ropes.

On the Wheeler Auditorium stage yesterday at the first TEDX event in Berkeley, they joined forces again. Ross entertained us as he created energy and synergy on-the-fly with his lasso, while Eric performed a wondrous jazz piece. Later, they are joined by TEDXB organizers and volunteers on-stage.
