This version is a slightly modified improved version of an earlier one that was published on this website in 2002.
When viewed in different fonts, ASCII-art sometimes does not work. For that reason, and to avoid annoying people using screen readers (who would hear something like: “R” “R” “R” ad infinitum), I offer it here as a graphic.
Comment added : Notice how each letter of the logo is made of smaller versions of the same letter. This type of self-reference is known as the Droste effect, a visual example of a strange loop.
