Hawaiian Kociemba
On April 1, 2016 The Cubicle posted a video titled Michael Humuhumunukunukuapua'a's International Debut.
This video featured several solves with solutions that the community couldn't match to any known method.
The same day, Stachu Korick shared a bit more on the mystery story on Reddit
In the Reddit thread, user vikktorz provided a reconstruction of a solve from the video.
Brayden Mossey (user wir3sandfir3s on speedsolving.com) started a discussion with their interpretation of the method in the video. Those steps are now solidified as Hawaiian Kociemba.
Multiple variants were proposed in the first speedsolving.com thread and on the Hawaiian Kociemba website.
The Hawaiian Kociemba website was created by Cubingcubecuber who produced some community interest in the method after starting his Quest For Sub 10 Hawaiian Kociemba thread on speedsolving.com
On April 23, 2016 The Cubicle posted a video explaining the April Fool's joke
The video also described the solves. Rowe Hessler was the solver in the video and he performed CFOP solves with random alterations to the steps in the later part of the solves. The interpretation by Brayden Mossey was based only on the first solve in the video where Rowe left out a cross edge before getting to PLL. The remaining two solves in the original video have no resemblance to the first solve interpretation that became Hawaiian Kociemba.
In 2020, Cubincubecuber proposed a version of Hawaiian Kociemba for big cubes, named HK+
