While this new "maze" compositor for Wayland likely won't see much in the way of real-world use besides being an interesting Qt-based solution for demos and for showing off Qt capabilities on Wayland, it is one of the most original Wayland-based demos to date.
The Wayland Maze compositor simply "showcases the use of qtwayland's compositor API for creating a 3D wayland compositor. The soldier images are from the Wolfenstein 3D Texture Library." During the video demo embedded below, there's Wiggly, a terminal, Qt Creator, and other Wayland surfaces being rendered to the walls of this Qt 3D maze.
Those wanting to check out the source-code to this new Qt Wayland compositor you can find the code on GitHub.
