Network Boxes is a CarnivorePE client. Utilizing this packet sniffer developed by Rhizome.org the piece listens to wireless network activity extracting the IP address and port number from each data packet transfer. Visually, each packet transfer is represented by a new box object whose color is defined by the port number being accessed and then stacked linearly according to IP address. In this way, every string of box objects is representative of one network user's IP address and the color the type of network activity of that person.
