Fx153 is a composite conduit, one of the original sixteen Herschel conduits, discovered by Paul Callahan in February Category:Patterns found in 1997. It is made up of two elementary conduits, HF94B and BFx59H. After 153 ticks, it produces an inverted Herschel at (48, -4) relative to the input. Its recovery time is 60 ticks. It can be made Spartan by replacing the snake with an eater 1 in one of two orientations. The Fx153's output Herschel is the opposite colour from the input Herschel, so replacing an Fx77 with a Fx153 will change the color of all subsequent output gliders.
In the pattern shown in the infobox, a ghost Herschel marks the output location.
