protocoLED

This concept involves an LED light that is to be fixed to a bottle, whose light intensity will be controlled by the turning of the cap. As the cap is opened, the LED turns on, and vice-versa.
Again, this idea is simple in execution, but its interaction with its users can be varied, in terms of orientation, form, material, light diffusion etc. The advantage of this would be to use recycled material in an interesting and aesthetic manner.
