illucia is a patchbay controller by chris novello. It lets you use physical cables to connect things like videogames, music software, text editors, synthesizers, and more. It has a free suite of interconnectable games and software, plus it speaks OSC so it works with many existing programs.
Also, illucia is open source everything (built with Arduino and Processing), so you're free to build, reimagine, remix, or replicate in any way.
