I don't mean to sound snarky in the least, genuinely curious, but haven't a large proportion of tinkerers, especially with an EE bent, tried to put a simple lisp interpreter on some limited hardware at some point in their lives? I certainly know that a bunch of people learning FPGA programming in a user group i once belonged to all tried to put a lisp machine on one after working through the last chapter of SICP, and there's that lovely article about lisp interpreters running on old JPL probes back in the day. What about this makes it revolutionary?
Of course it's not revolutionary. Lisp is the past technology of the future. And indeed lots of people have done things like this, with Lisp or Forth or Basic or microPython or Lua.
I believe a very early Raspberry Pi prototype was an Atmel chip that ran a Lua interpreter with bit-banged VGA display. It was extremely cheap but ultimately deemed not capable enough.
