Smart Fairy Tale @Raspberry_Pi #PiDay #RaspberryPi

Using community sourced materials, Berlin-based installation artist Niklas Roy and interaction designer Felix Fisgus have created the amazing Smart Fairy Tale. Here’s more from Niklas Roy: “Smart Fairy Tale” is a remote controlled story machine. A little red ball rolls through a maze of transparent pipes. Interrupting light barriers along its way, the ball triggers the movements of numerous animatronics. Different track switches inside the pipe system determine the path of... Read more
