I’m digging the way you turn on this fiat lux lamp by designers Constance Guisset and Grégory Cid. In place of the standard light switch, you place an orb under the lamp, which then (presumably) uses a magnetic field to hold it in place. When you are done, you simply pull it away and the light goes out.

I think it would be awesome to make this into a timer for the light- the lamp could have a control system that slowly lowers the orb, until it gets far enough away that it drops to the floor and shuts off the light. Anyone want to try it? [via notcot]
