I think media artist Paul Notzold is awesome and very creative. He has amazing ideas, which you can browse on his site, but I like his project, TXTual Healing, the best. It involves audience participation. He projects an image on a wall, roof, whatever, and passers-by can send texts to a certain phone number and each text is displayed in the image for the public to see. Here are a few pics out of hundreds that are on the project site.
Sometimes, he adds a prompt, like in the image above, which says, “Who are you afraid of?”. I would like to see a prompt that says, “I have a confession…”.
