We only come out at night
I discovered this tucked away in the exhibition section of the Processing site. As they say on their site, it’s “an urban graffiti project involving interactive public projections”. Essentially they find a site and set up hidden projectors and project these “jellies” onto a wall. If the jellies get angry, they grab the shadow of a passer-by and eats it. The next day, they move onto a different site. They’ve also set up a site to help promote and create a mythology.
