For all of you web designers out there, MiniAjax provides a well put together list of simple and nice looking downloadable dhtml and ajax code.
MiniAjax has screenshots and descriptions of a good number of scripts. If you are looking to add a heatmap to your site, or to add a floating and aesthetically pleasing window to your site, MiniAjax is the place to go. A useful poll script, an RSS boxes script and a dragable content script are included here as well. This site includes scripts that enable many of those little effects that you have found so useful and that have defined web 2.0. Overall, there are probably close to 100 scripts laid out for your viewing pleasure.
As one would expect of a site designed to be a showroom of good looking scripts, MiniAjax is clean, well organized, provides just enough information, and provides really useful scripts. Two thumbs up.
