I just discovered sIFR, which has apparently been around for a long time. It’s really nifty, actually. A lot of the time you want to display headers on your site formatted in some fancy font, but chances are good that most of your  visitors won’t have it. The general solution is to use an image or Flash app to display it, but this causes usability and SEO problems, since the visually-impaired and bots can’t read the text, since it’s not text at all.

sIFR solves this by having your page be normally-formatted, but using JavaScript to overlay a Flash app with the desired font where the browser supports this. It seems like it was designed by people like me who hate Flash apps and images of text all over the page, because it’s incredibly slick and you wouldn’t know it was happening unless you happen to notice a fancy font being displayed inline on a page.
