A lamp that mimics the moon

The 'Eclipse lamp' by Vico Magistretti for Artemide (Milano), 1967

Two years before man's first landing on the moon, Vico Magistretti designs for Artemide the 'Eclipse lamp', an icon of Sixties Design and the Space Age.

The lamp has two sphere shades, the inner one rotable, so one can have different lights like the changing ones from the moon.

Measuring time by the Sun

For thousands of years, people used sundials to tell the time. The first sundials were used more than 3,500 years ago in Egypt.
A sundial is a device that measures time by the position of the Sun.
In common designs such as the horizontal sundial, the sun casts a shadow from a thin rod or a sharp, straight edge, onto a flat surface marked with lines indicating the hours of the day.
As the sun moves across the sky, the shadow-edge progressively aligns with different hour-lines on the plate.
