Gravilux

Gravilux is an interactive musical starfield visualizer: it’s a combination of music, animation, art, and science. As you touch the screen, gravity draws simulated stars to your fingertips. You can tease and twist the particles into galaxies, or explode them like a supernova. You can color the stars by their speed, and make them dance to the music from your play list. You can change parameters including gravity and number of stars, and enable antigravity and color. Multiple fingers and multiple people can touch the screen at once, collaborating or competing. Gravilux was first released as a work of interactive art by Scott Snibbe that was only available in galleries and museums that became a best-selling hit on other mobile platforms and inspired Björk to work with him and his studio on the first App Album: Biophilia.

"Apps like Gravilux awaken an 'Avatar'-like sensitivity to electricity in the body, power in the palms and general connectedness." —NY Times
"Of the millions of apps out there, none quite capitalize on the sheer fun and beauty of interactivity the way that Scott Snibbe’s do.” —CoolHunting
