Today I found some time to pick up the client side of my zero-dependency wayland project. I now have a single < 1000 line go file that can be used to create a window backed by a shm buffer, and listen to keyboard and mouse events and have it running in both my Nyctal compositor and the Weston reference compositor (video attached).
Warning: the video is a small square that rapidly flashes random colors as I am pressing the control key.
