GUIDs have always been a passion of mine. I guess it's that they are so ugly, you've got to feel sorry for them.

As some of you remember, I tried to make a quick buck selling a GUID (pic1 & pic2) on ebay a few years ago. That may be a venture I fall back on when I retire. In the meantime, some technologists, using the latest presentation foundation (WPF/E) have built GuidMarket. Check it out.
