ansaconv (ANSI art converter) converts ANSI art so that it displays properly in a terminal emulator with a character set other than cp437.
It's still a work in progress that doesn't display everything properly and lacks some of the planned features. The main benefit currently is that the art pieces display correctly in a terminal wider than 80 characters.
You could download a copy of the Sixteen Colors ANSI and ASCII Artwork Archive from their artpack repository and add something like this to your shell startup files: ansaconv ~/sixteencolors/$(shuf -n 1 ~/sixteencolors/list.txt)
