Robert van Engelen released a complete Lisp interpreter implemented in just 99 lines of C, featuring 21 built-in primitives, garbage collection, and an interactive REPL. He proved its small size by running it on a 1990s Sharp pocket computer, and published the free source with a line-by-line explanatory article.
