> a non-exhaustive list of projects that create super-minimal interpreters

One of the items on that page is described as "25k lines of asm". That's the problem with 'tiny'. It means different things to different people. This FORTH thing however appears to be an exception. You know you're playing the game at a different level when your entire app can be statically linked with all its dependencies and still be small enough to fit inside the master boot record of a floppy disk (i.e. less than 512 bytes). I just wish I could figure out how to use the thing.
