I just walked by a co-worker’s desk while she was on break and saw the most adorable DDC screensaver ever! Ok, it’s the only DDC screensaver I’ve ever seen, but hey, it’s still cute.
Available from OCLC (of course), this screensaver features a cute, yet sinisterly grinning (IMO), decimal point-guy bouncing around. The screensaver also goes on to show each class and a few select entries “Humorously illustrated”.
Go download it and waste time learning your DDC!
