"Orbit" lets you shape an evolving galaxy of up to 5000 stars with a simple touch. Each star exerts a gravitational force on every other star. Ordinarily calculating the resulting 25 million gravitational interactions would be impossible in real time even on a powerful desktop computer. However using a highly optimised algorithm the beautiful complexity of large scale "N-body simulation" can now be presented at interactive frame rates on a hand held device.
