The beacon is the third most common oscillator (after the blinker and toad).[1] 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.
As an eater
A beacon can be used as an eater for any even number of gliders, using the boat-bit reaction. When they collide into it as pictured below, the first glider of a set will be transformed into a boat, which will then be destroyed by the second.
