Wow, that effect's awesome, Jeeves. Thanks for the link.

FWIW - No browser since Netscape 4 has a problem with single-color transparency 8-bit PNGs. As noted above, Internet Explorer (alone) has problems with 24-bit PNGs, with or without alpha transparency.

(To be fair, most issues are fixed in IE 7. It still suffers from a color shift if the gamma value is left in the image, though.)

This reminds me of a CSS Zen Garden entry. See this page: http://www.askthecssguy.com/2006/11/props_to_the_css_zen_ocean_div.html (remember when you view the entry use Opera, Firefox or Konqueror, IE and Safari don't work). Note the diver on the right and how his little light works the deeper he goes.

I wrote a hack to work around the problems in IE when displaying PNGs, see: png alpha hack.

I'm not sure what you mean about Vista but I think that yes, this would work. Transparent png's can be a bit tricky, especially in IE 6 which doesn't support the alpha transparency. There are ways to get around that though.
