To anyone who wants to play around with lisp, I recommend downloading the emacs text editor. Just open it, navigate around with the arrow keys. Type an s-expression, and place the point after the ")". Then type Ctrl-x Ctrl-e, and the expression will be sent thru read -> eval -> apply. Fun to just play around with.
