Discovered by Robert Wainwright
Year of discovery 1994

On October 10, 1994, Robert Wainwright discovered a period-24 oscillator shown below that uses a reaction where two blinkers get converted into a domino spark via a transparent beehive. The reaction works with any blinkers, allowing to be used at other periods, but no official name has been given to it. Its minimum repeat time is 11, but periods close to 11 are likely to have the reaction interfere with the next blinker.

Due to the nature of the reaction, sometimes it works but is completely unusable, such as in this p63.
