For my mozilla using friends...
If you need to ever show why you use Mozilla; show the "IE is good enough" crowd: this page
, which demonstrates seamless compositing. If you have IE 6.0 or earlier; you can show them the IE hash-and-trash for comparison. If they're the kind to be wowed by neat effects, and they know HTML; challenge them to duplicate the effect using only HTML and CSS1 in IE. They'll fail. Why? IE, as all good Mozyfans know, is NOT standards compliant and Mozilla is especially in CSS1 and PNG support.
Wouldn't this effect make a really neat journal style? I'd code one, but my ability to create LJ styles has lapsed.
