Fish screensaver	The fish screensaver simulates the swarming strategy of a shoal of fish. Each fish attempts to maintain a safe distance from the nearest one it can see. You can change the model to herd behaviour in which animals head for the centre if they are beyond a safe distance. Fish turn yellow when they feel they are too far away, and blue when they are too close. You can configure the speed and strategy of the fish from the screensaver control panel (you can also change the fish speed with the arrow keys when the screensaver is running).

The fish screensaver simulates the swarming strategy of a shoal of fish. Each fish attempts to maintain a safe distance from the nearest one it can see. You can change the model to herd behaviour in which animals head for the centre if they are beyond a safe distance.

Fish turn yellow when they feel they are too far away, and blue when they are too close. You can configure the speed and strategy of the fish from the screensaver control panel (you can also change the fish speed with the arrow keys when the screensaver is running).
