LisPi #0 – Lisp environment on bare metal [YouTube]

I found this demo of a bare-metal Lisp, but I can't find much more about it. I hope he releases the code! Seems like it has been developed more than upon first appearance - debugger, custom opengl graphics library, and drivers with a shader compiler.

For now, he has written the USB driver and SD card reader in C, but he plans on moving it all to Lisp. I love the shader compiler example, and the minimal look.
