Gaze your eyes upon Unnumbered Sparks, the interactive artwork of artist Janet Echelman and Google’s Aaron Koblin.
What’s not obvious to the public is when you look at the sculpture, you’re actually looking at a web browser. The interactive lighting is actually one giant Chrome window, stretched across the 300-foot long sculpture with the help of five high-definition projectors. To interact, visitors open a website using Chrome or other modern mobile browser on their smartphone or tablet. After selecting a color, they use their fingers to trace paths along the surface of their device, which are then projected onto the sculpture in real-time as colorful beams of light. The result is a crowd-controlled visual experiment on a giant, floating canvas.
