A finite object on the outside contrasted with an infinite space on the inside. All the viewer is able to see inside the box is light, their eyes have no reference points, which gives them the perception they are staring into infinity, no matter which way they look.

The Red Box has two covers: one which is illuminated by artificially coloured light, and the other by natural daylight which is intended to show the gradual shifts in tonality and temperature which occur over the passage of a day. The intent is to sharpen the viewers’ eye to the small changes in skylight otherwise rarely perceived. The museum is a large scaled version of the same principle.
