Spry?

AJAX is a combination of web technologies widely popularized by Google. Spry is Adobes brand new AJAX Framework, directly competing with other libraries such as Prototype & Microsoft’s Atlas. It is very easy to use and comes with some great animation and visual effects. Some very powerful uses may also be in the works – such as AJAX application generation from Adobe’s Flex Builder. AJAX is a great way to develop rich internet content easily and inexpensively, and with more and more libraries coming out – developing AJAX is painless.
