Spotlights inside the room shine out through the windows onto mirrors outside. The light bounces back into the space and onto a projection screen that divides the room. Traces on the window panes and irregularities in the centuries-old glass become visible in these projections, making the materiality of the windows explicit. The lights have been fitted with color-filter glass that make the projections appear to be different hues depending on the angle at which they are seen: blue from one angle and orange from the other. Viewed head on, the colors mix at the center. The shifting tones draw viewers in to examine the projections from up close and drive them to move about the room.
