FieldLines is a screen saver that simulates the electric field lines emitted by charged particles. In this screen saver, ions move around the screen and bind to the lines of other ions as they get close and unbind as they move away. As the original author has said, physics never looked so good. FieldLines is available in English, French, and Italian.
