Effect.Transfer I really like this effect! It reminds me of ones I'd seen on the terrific TiddlyWiki app as well as the Ajax-y BloxPress blog system for WordPress. It may come as no surprise, in fact, that the effect was developed by the author of BloxPress... as well as numerous other cool web goodies. This effect is intended to augment the collection that comes with Script.aculo.us, and the author provides several useful demos on this page.
