An inverter (or inverting reflector) is a device which can be used to invert the presence or absence of spaceships in an intermittent stream of spaceships. The device must be a gun whose period matches the base period of the stream, since if there are no input spaceships then the device must produce spaceships as the result of the inversion. Typically the spaceships are gliders, and the inverter is made from a glider gun. Inverters provide a way to produce a NOT logic operation on a stream.
