From the title alone I tought it will be another FORTH interpreter implementation article, but I was happy to see someone actually using it for anything besides proving their interpreter with a Fibonacci calculation.
Yep, given that implementing Forth is so easy (easier even than implementing Lisp) pretty soon nearly every Forth programmer decides to take their turn doing it themselves.
There's another front page article right now with someone using it in a very cool way.
