- A wedge of glass, in cross-section a right-angled triangle hung from the shortest side, with light passing downwards through the shortest side, hitting the hypotenuse, and bouncing out near-horizontally from the third side. The top of the wedge has ridges for setting it into a frame, and some of the light misses the wedge and continues downwards. (en)
- Two black-rimmed squares of glass. Above, one with rows of identical small prism ridges. Below, one with three pendants like those in the last image, but increasing successively in size. (en)
- Large high-ceilinged space with round iron arches, covered in glass-dome skylights, floored with vault lights, clock central in foreground. (en)
- Like image one, but the three different-sized prisms send the outgoing light off on parallel, not overlapping, courses. (en)
- Large bathroom with chairs and a free-standing radiator, lit by flat skylights (en)
- View of the underside of the vault-light floor, supported by tapered concrete beams (en)
- A transport station with benches under a roof in the middle of a city square inset with inconspicuous rectangles of vault lights (en)

- Lenses with multiple rows of pendant prisms. Above, identical prisms; below, three dissimilar prisms sizes, for light dispersion. These lenses are armoured with malleable plastic (en)
