A continually changing sequence of circles and arcs of light plays out along the curved walls of a darkened gallery. This light show emerges from a black box into which a spotlight is shining. By peering through gaps in the box, viewers can see the construction inside that creates the patterns of light on the wall outside: an array of lenses, mirrors, and colour-effect filters. As the filters rotate, the projected circles of light slowly elongate and distort, wax and wane, changing in hue from wan blue to an intense solar yellow. The entire space appears to move and transform, as visitors step into the light and cast their own shadows into the composition.
