Rolling robotic balls maker Sphero is set to launch a musical motion-enabled ring that catches tunes of colors. Specdrums is a ring that plays musical notes every time you touch it with a color. When tapped or pressed against a color, the ring communicates it to the paired smartphone app, which converts the color into a musical sound. The iOS and Android-friendly app called ‘Specdrums Mix’ is designed to work with multiple rings at once. Two packs of Specdrums rings are moderately priced at $100 and available at Sphero’s company website.
