Interesting lecture. The base concept is slightly different: My
"picture" returns a list of lines when called, while his picture draws
itself when called, but the rest is the same. But I don't like the Scheme
notation, because for me it is more clear to see a "funcall" when a
function is being called.

Another good part: at the end of the lecture he compares the top-down
methodology with the "levels of languages" methodology and explains why
it is more robust to use embedded languages in Lisp.

Regarding the picture: Would be nice to enhance the program to produce a
more exact reproduction of the original picture, filled with color, with
curved lines and recursive to level n (see "Square Limit"):
