I came across jComponents, a set of custom tags that provide DHTML-based UI widgets (tabs, accordions, trees and more). I have yet to use these in a project but they look very cool.

While browsing the demos I came across the ColdBakedBeans sample app. The app is a little utility to help make CFC "beans". A good demo of the jCompenents suite and it could save you some time/typing when creating your bean CFCs in Mach-II.
