As part of Physical Games & Interactive Media, I created a clock and art piece that responds to the viewer. A motion sensor embedded in the clock detects a person's presence and reacts accordingly. In addition, an interactive art piece changes based on feedback from the clock. Together, the two compenents are meant to encourage exploration and play.

The two main components of the piece include a click and a digital display. The two are not obviously related, but the relationship becomes clearer as people interact with the clock. At the heart of the interaction is a motion detector in the center of the clock that controls the display. When no one is present, or when no motion is detected, the clock displays the correct time and cycles through a series of seven different colors. Once motion is detected, the clock shows the incorrect time or no time at all. As such, people have to stand still long enough to fool the motion detector before they can see the time.

At the same time, the digital display is an image of colored bubbles that move and collide naturally. Every time motion is detected, a new bubble is created and all the bubbles are disturbed as if a gust of wind blew through the image. The color of the newly created bubble is the same as the color of the clock at the time of the detected motion. To avoid a build up of too many bubbles, each one has a lifespan of 5 minutes - after that it pops (expands and disappears).
