Called Sketch and intended for use by designers, the lamp head twists upside down to lie flat on the desk.
With the light source pointing upwards it can be used for tracing, accommodating A4-sized paper.
Here's a tiny bit of text from the designers:

The idea is simple. Turing the lamp and put it upon the table. Than you get a light table ready for sketch.
