Fast forward force field
A reaction found by Dieter Leithner in May 1994. In the absence of the incoming LWSS the gliders would simply annihilate one another, but as shown they allow the LWSS to advance 11 spaces in the course of the next 6 generations. A neat illusion. See also star gate. (Leithner named the Fast Forward Force Field in honour of his favourite science fiction writer, the physicist Robert L. Forward.)
