I just discovered an entirely different kind of juggling that I have never seen before: balls roll about the body, instead of whirling through the air. (Penn Jillette mentioned it while being interviewed by Marc Maron.) Apparently some of the skills of Contact Juggling are ancient, but most of the moves have been invented since 1980. Here is an elegant demonstration of Contact Juggling: the artist fiddles with several balls at first, and then, after a short interlude, does wonderful things with a single ball. Sometimes the ball even seems to hang in space, unsupported.
