Interesting collection, but as the intro states: Any kind of CSS goes, as long as it's supported in at least one browser.
More impressive and useful would have been a reasonable floor above which the tricks were guaranteed across browsers. ...or at least a compatibility note next to each technique. For example, IE 8 can't handle rounded corners, so infinity, egg, packman, talk bubble, etc do not work at all. Version 8 is as high as Windows XP users can go with IE, so there's a lot of IE 8 out there still.
