Mike Davidson has created quite a stir in the blog community with the release of sIFR (or long: Scalable Inman Flash Replacement) especially among designers that want to have more options than Arial, Verdana or Georgia in their HTML websites. To make it short: sIFR uses SWF files to dynamically display texts - especially headlines - with embedded fonts. This alone of course would not make news as it has been done before - the interesting part about it is that it replaces the original headline via CSS in such a way that it fits itself in exactly the same space and tries to create an optimum layouted text. See an example here. On browsers that do not support Flash users can still see the original HTML headline.
The latest version is sIFR v2.0b.
