Drift Grid (I) is a large wall piece containing 16 dynamic panels. The shapes on each panel slowly drift upwards, changing their look and behavior as they cross the membrane between panels. When viewers look at a particular column of panels, the shapes on that column slow their movement: they continue to grow, but no longer drift upwards. Although the columns begin identically, they drift over time in reaction to viewers' gaze.
There is a non-interactive version of this piece, that plays as a video loop.
