The beacon is a common oscillator, composed of two diagonally touching blocks. It was found by John Conway in March 1970.
The beacon is the simplest on-off. Its rotor, known as diagonal on-off, can be supported by several different stators: the two next-smallest are seen in eater plug and 21P2.
A beacon in the right phase can make a boat-bit.
Commonness
The beacon is the third most common oscillator in Achim Flammenkamp's census (after the blinker and toad).[1] It is also the thirteenth most common object on Adam P. Goucher's Catagolue.[2]
