BASIC is another simple-to-implement language, especially if you go for something like tinybasic. I had fun recently writing something like forth. I'd probably like to try doing it properly next time - using a proper return-stack so that `if` and similar primitives can be implemented in the language itself, rather than in the hardcoded fashion I have at the moment.
