Some people compare FORTH with game GO or philosophy ZEN. Very simple rules. And you build an own universe. And all of this fits into a very small size. As you also mentioned.

If you want to play with an online FORTH interpreter:

FORTH is a very old and unique language. Different from all the others. You can find it even in the space-ships.

I created a FORTH like language some years ago. Also fun.
