Of course, this being emacs, you have a practically infinite number of ways to make it look pretty. You could use the built-in emacs magic (as described above), or you could write some lisp that renders your text in, say, 3D, on an auxiliary window. You could also write some CGI scripts in Phase that let you diddle your emacs from your favorite HTML browser (and use CSS to make it look pretty).

This being emacs, the possibilies are endless, so go out and make some happen!
