1、MooTools Mocha UI（基于MooTools和Canvas构建）
网址：http://greghoustondesign.com/demos/mocha/简介：Mocha is a MooTools user interface class made with canvas tag graphics. This is an on going exercise to help me become more familiar with both MooTools and the canvas tag. See the windows to the right for more information。
2、ModalBox 网址：http://code.google.com/p/modalbox/简介：ModalBox is a JavaScript technique for creating modern (Web 2.0-style) modal dialogues or even wizards (sequences of dialogues) without using conventional popups and page reloads. It's inspired by Mac OS X modal dialogues. And yes, it may also be useful for showing bigger versions of images. :)
Basically, ModalBox is based on GrayBox technique by Amir Salihefendic. But you can find a lot of similar techniques around the web: Lightbox JS, Lightbox gone wild, ThickBox etc.
There also a clone of ModalBox, the MOOdalBox, written on great and lightweight Mootools Framework.
