These 3 panels stretch across 3 scenarios: an internally lit panel, a panel half lit and half behind wall and a panel fully behind wall. The glasses chosen had to work across all 3 scenarios and also as a set. Cloudy Kokomo was used for the main background glass. It has slight translucency so lets light through but also has enough obscurity to work well with a brick wall behind. Iridescent waterglass was used in the borders again this is see-through but also retains its iridescence when light is blocked from behind. Silvered coloured glass was used in the features where the brick wall was behind.
