I like the way the page headings are done over at hypothecate (go there and press reload a few times). There is a little javascript trickery that generates a kind of “drop shadow” effect, makes some letters randomly “boxey”, and formats the page sub-heads vertically. If current browsers supported it, you could probably achieve a similar effect using the text-shadow property defined in CSS2.
There is a javascript trick to emulate the behaviour of position: fixed in IE6. I suppose it could be possible to emulate text-shadow in a similar way. I also suppose if this was a good idea someone would have done it already. ;-)
