solar mobile by Jan from germany

The Solar Mobile playfully and gently displays two aspects of motion - movement and energy.

The movement of the mobile is a subtle but direct reaction to its environment, be it the airflow of passers-by, or the ascending warmth of people standing near it.
The embedded solar panels are ideally lit by sunlight through a window or skylight, and directly send the generated electricity to a grid of LEDs, with the number of lit LEDs depending on the amount of energy generated. The display of seemingly random illumination shows the importance of motion relative to time and postion.
