 * Windows 95 by way of an AOL trial CD. This is a deliberate single-world

 * existed and faking one would read as a bug rather than a choice.
 *
 * The list icons are drawn from each list's own theme swatch, so the desktop
 * doubles as the sample board — you can see what a list looks like before you
