Those aren't techniques, that's a list of 75 scripts, some of which are full-on applications (AjaxIM). And what on earth is the point of using JavaScript to make, of all things, CSS sprites? Those were meant to be a substitute for JavaScript image replacement in the first place, and to reduce page load times.
ironic that you're critiquing the use of javascript for css sprites when the article was written by one of the guys that coined the term and mainstreamed the technique.
edit: but yes, its a post designed for cut-n-paste coders.
Dave Shea's article on sprites is a great extension on the original method. If you want simple spirtes, CSS works fine, but he is just making it a bit sexier.
