Here is some of my work and some of my experiments:
Games, Tools, and Utilities:
XBM stuff - doesn't work in IE 6 in XP sp2 because they disabled XBM support.
Demos and Experiments:
[N4, IE] Reflecting Pool - a shimmering water effect for any entered text. Very cool... I might add it to my pages someday. [N3+, IE] Fake style change "rollover" or "A:hover" effect that works on Netscape 3 (and probably earlier) [N4, (IE)] Netscape Hover Style. Make a:hover style work (almost) in Netscape 4 (a.hover, actually)
[N3?,IE] Radio Question Validator [submitted Aug 29, 2001, listed Feb 20, 2002 (2002-20-02!)]. Original Sample One user already noted that there is one vulnerability in the script... if you name your radio buttons with numbers it won't work.
