This video on Youtube: https://www.youtube.com/watch?v=_uKAasiCYCg shows a move by move playout of the famous "heart" long ladder composition by the late Nakayama Noriyuki. It is an expression of "kansha" (gratitude), with each pro player at his/her home making one or two moves in the ladder. Some of the participants are famous pros, e.g. Shibano Toramaru Meijin, and the 11 year old Nakamura Sumire 1p makes the last move in the ladder. Her partner at the go board is her father, Nakamura Shinya 9p.

Very cool, even Antti was part of it!
