The lamp of a sheet of paper.
This lamp is made of a sheet of paper with many parallel slits cut
at an angle. When rolled, the paper makes a smooth barrell-shape, as a
result of the balance between its own weight and the tensile strength of
the paper.
The different patterns of the slits create various and complex moire
effect, which changes its appearance according to the point of view. It
overlays a new visual pattern over the physical shape of the lamp.
