Rimvydas Jasinskas has added the OpenBSD versions of banner(1), boggle(6), and tetris(6), along with additional fortune(6) material.
Odd note: tetris(6) originated with a 1989 International Obfustcated C Code Contest winner, according to the man page, but I can’t find it in the 1989 list.
tetris must be John Tromp’s http://www.ioccc.org/1989/tromp.hint also here https://tromp.github.io/tetris.html
Good catch; I remember seeing the ‘tromp’ name but not recognizing what it was.
