@rl_dane it's a framebuffer program, I use SDL so I don't have to deal with x11 keycodes atm but I might port it to x11 if anyone needs it, but it's the same idea. It's a kind of VM multiplexer that only handles communication between uxn programs. Like emulating pipes between unix utilities. It's only a few hundred lines of code, it allows to bypass the host system to do uxn dev.
