We saw her back on a trip to AK in fall 2002. She is what I would call a performance artist. She can be easy to miss. She has a costume that has many ivy type leaves on it, so thick that you cannot see her underneath, even close up. It looks like she has 4 branches going down to the ground. When you see her standing against a wall, she really does look like a vine. It's only when she starts to move that you realize it is not a vine. She had a handler with her, we took a picture of her standing next to my DD, 7 at the time. Looking at the picture I would say the leaves extend about 8 feet high, maybe 4-6 feet across. The handler would not allow DD to touch her.
I wish I could remember where we saw her. Hope you can catch a peek.
My 1000 post, cool.
