Incidentally, I was the one who contributed #38 in the one-liner list. :-)

Rebol 3 has been free in both senses since its development. It is still in development by the community, but is completely usable. For instance, see my Rebol 3 tutorial (I started developing the tutorial a few days ago) running on a webserver running Rebol 3. The pages are created in real-time by a Rebol 3 dialect called JSID that outputs HTML and JS.

This is just one example of real-world applications for Rebol 3. And if you learn Rebol 3, Red is almost exactly identical.

BTW, I'd love to hear feedback on the tutorial. :-)
