These really haven't changed since the Lightning Sunset days. I wrote an individual paragraph for each of them before I realized that I was just repeating myself from 16 months ago. The common thread here is that they're all tiny apps which enhance the taskbar and the desktop in extremely logical, intuitive, "I can't believe it didn't do this by itself" ways.
I really love this visual style for XP; it's become one of lassekongo83's most popular, and deservedly so. Its most distinguishing feature, one which is inexplicably rare among Windows shell themes, is that it inverts the colors, giving Explorer, Notepad, etc. a dark-gray background against light-gray text. It is wonderfully soft on the eyes, especially late at night.
