sIFR (Scalable Inman Flash Replacement) is a method "to insert rich typography into web pages without sacrificing accessibility, search engine friendliness, or markup semantics". It’s been designed, scripted, tested, and debugged by Mike Davidson and Mark Wubben.

"sIFR is meant to replace short passages of plain browser text with text rendered in your typeface of choice, regardless of whether or not your users have that font installed on their systems. It accomplishes this by using a combination of javascript, CSS, and Flash."
