Homo Indicium is an interactive technology driven installation by Ioannis C. Yessios. At its essence, Homo Indicium is a database. This database contains information about people who have seen the piece and chosen to participate. The physical components to Homo Indicium are a visualization of this database. They serve as the interface for interacting with the database. Thru the interface the audience can access the information contained, or populate the database by volunteering their own information. Due to this volunteered information, Homo Indicium grows with each exhibition.

As you approach Homo Indicium you see a number of test tubes mounted on the wall. Upon closer inspection, you see that many of these test tubes contain hair samples. Each hair sample has a unique barcode directly below it. Tubes are held on 2 ft by 2 ft panels which hang from the wall. Each panel holds 20 tubes. A scanning station in front of the test tubes allows the audience to scan a barcode and view the information associated with that hair sample. Information includes a wide variety of facts, finger prints, and a voice print. An other computer station in the space allows audience members to add their information to the database. Although the information collected is of a highly personal nature, addresses, names, or government issued identification numbers are not collected.
