Gravilux is a work of interactive software art for the iPhone, iPad, and iPod Touch. With each touch in Gravilux, you exert a gravitational pull on a world of simulated stars. Though inspired by Newton's equations for gravity, Gravilux doesn't follow our universe's laws.
Gravilux is a combination of drawing, animation, art, science, and gaming. Gravilux was first released in 1998 as a work of interactive art that was only available in galleries and museums. Now it is available as an iPhone and iPad application.
