Maybe "mime" is not the correct term for what you were doing, but it was all I could think of. You were bringing people "out of themselves" on the stretching floor of center camp by creating silent, physical interaction using balls and other props. Your daughter (?) was also doing this. You were both very expressive and talented at this art.
I was the tall brownish/blonde, blue eyed man you interacted with right before you left center camp through the exit by the poetry reading stage. You said goodbye to a few people so I'm hoping one of them will see this. I was eager to hear the voice of and meet the person behind the charade, but you left so abruptly I did not get the chance. If you, or anyone who knows you, gets this message, please respond. I am just curious to know more about two unique and interesting people.
