Oh yeah, this combo is actually one of the better modes in Emac-land. Whenever I see yet another ASCII art link posted here, I just gaggle cos Artist mode is that good.
Like many emacs things, there more than one. There's also picture-mode. I haven't used either very much, but my sense is that artist-mode is more mouse-oriented and possibly supports more sophisticated drawings but picture-mode may work better in terminals.
