Fish And Plankton (2009-Oct-12 8:48 EDT)

This is a simulation of an aquarium where male fish, female fish, and plankton are roaming. When they bump into each other, some events happen.

A nice and entertaining way to introduce ecosystem.

Very detailed simulation of fish’s in Aquarium. The male and female fish move, produce offspring, and die. Females (only) eat plankton when level of hunger is right. I enjoyed playing with it and love the idea, but have one problem and few questions: With many males, the population grew very fast and I lost control on my machine; neither the stop button nor any of the buttons on the top of the screen worked, for a long time. Consider limiting the number of players, or put a warning. I wonder why you chose to have only females as offspring. Why the food has no effect on the life of the fish: male don’t eat at all and both genders don’t suffer from lack of food.

Project is very inspiring, I get lot's of ideas for further study with graphs and other statistics. The projects sound effects make me want to change something with the default sounds in Etoys, tho ;-)
