An amazing lamp concept called RIMA and created by Matthias Pinkert. The lamp looks really good and interactive. Below you have the description from the designer:

Based on the metaphor of a window curtain, tangible action has been implemented into RIMA’s design. Depending on how far and where the user draws that curtain, the illumination of the room will change. Thus, the user can actively decide the amount and the position of the light incidence.
The rings, almost floating along the light rail, put two metaphors in redundancy, aiming directly at the motor function of the human hands: drawing curtains and moving balls on an analog calculator, a “so called” abacus. A lit area is drawn directly by hand. Sitting on top of the desk surface on thin poles, the illuminant reminds of a classic neon tube in grasping height, giving RIMA a semantic touch.
