”’Solar Equation’ is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing.
The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun.
Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations.”
