A nice screensaver.
A friendly time with fish in an aquarium.
An example of strange coherence in our world.
Behavior of flocks is fascinating viewing. A simple rule for each individual make the shared knowledge of the flock. The flock together can see more, do more and make more.
In this App fish is schooling. Each fish knows that it must swim faster when there is light on it, but the fish don’t know where to swim. You are the master of the spotlight. It appears that the flock, after a while, will move outside the light to a more dark and comfortable spot. That is the opinion of the flock in this world.
This flock phenomenon may be a fundamental rule of intelligence of our world.
