"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.
"Germs" and "Germs FREE" just released! - the liquid physics engine of "Gloop" employed in a game of microbial conquest. Also by RunSwimFly: Gloop, Gloop Lite. Visit www.runswimfly.com for details and video links.
