Gathering, is a networked interactive video installation commissioned by and permanently installed in the Pittsburgh Childrens' Museum. Visitors see themselves reflected in a video projection in front of them. They can move, kick, group, and bounce forms falling from the top of the projection. These shapes contain a live video feed from the adjacent projection space. Thus, the visitors in the pink space can manipulate the blob-windows which look out onto the blue space. Likewise, users in the blue space can manipulate their windowed views of the pink space. Participants use their entire bodies to engage in a mediated communication between different spaces exploring new types of visual and physical communication.
