Hi, I am from Turkey. I have a project about a fish aquarium software(like 3d aquarium scren savers) that can interactive with a montion sensor. If montion sensor detects any montion(maybe plugged to pc serial port) all of the fishes will be scared and hide(to simulate a person came very close to aquarium). And one minute later, all of the fishes come back to normal life. we can talk about the price for this job. thank you.
