sIFR - Scalable Inman Flash Replacement
A team of dedicated web developers have put a massive amount of man hours in designing, scripting, testing, and debugging a method to insert rich typography into web pages without sacrificing accessibility, search engine friendliness, or markup semantics.
You can now use your coolest fonts to create headlines or text without having to create a new image every time. And it’s fully accessible to screenreaders and other assistive technology. This can all be done using a combination of javascript, CSS, and Flash.
These great guys released sIFR to the world as open source, under the CC-GNU LGPL license, so anyone can use it free of charge.
