The Last clock displays a space's history and rhythm. Trails behind its hands paint the clock face with a video feed, creating a mandala of archived time. The Last clock began as an investigation into representations of time. The goal was to use the mutable properties of digital technology, hoping to create something aesthetically pleasing, interesting, and ever changing without having to succumb to randomness. The clock reveals the rhythm of events and spaces. It provides a record of and a means of reflection for what is happening and what has happened. With the Internet-connected streaming version, the clock can connect two or more remote spaces so that people feel a sense of each other's presence. The clock does not show precisely the activity in the space, just a filtered version of it. Beyond being an aesthetic object, Last serves a real purpose as a display that shows an overview of a given space's dynamics and history. By borrowing the form of a traditional analog clock, Last becomes an easy-to-read visualization of complex information, which includes the type of activity captured, the pace and volume of motion, and the point in time that this activity happened. it shows all this information in a continuously updated, live, single image.
