Fore and back (or complementary blinker) is a period 2 oscillator that was found by Achim Flammenkamp in July 1994. It is about the 38th most common naturally-occurring oscillator, being less common than boat on spark coil and griddle and block, about as common as 21P2, and more common than trans-block and long hook eating tub and trans-beacon down and long hook.[1]
