You will never know that rocker switches can be an artwork display.
The artwork is designed by Valentin Ruhry, a Austria artist who is well known for his sculptures and installations that built out of industrial materials. This work is made out of 4,750 illuminated rocker switches as a message board. I don't know if the message board is interactive or not, but it is still fun to "write" something though the light-up switches anyway. I bet some kids who love to play with the rocker switch will be amazed by the massive board made from rocker switch. But I'm more curious about one thing: how much does it cost when you buy these much switches at one time?
