A track is a path made out of conduits, often ending where it began so that the active object is cycled forever, forming an oscillator or a gun.

| An example closed track producing a period 658 oscillator. Starting with a Herschel (bottom center), it cycles through Lx86, HFx58B, BNE14T30, Snark, speed tunnel and L112 conduits. The eater at the bottom can be removed to create a gun. (click above to open LifeViewer) |
