The session on creating modules for Dashboard was full to overflowing. Are they widgets or gadgets? The name is "in transition". Personally, I think "widget" is too general and already overused.

Widgets carry a lot of the lightweight feel of desk accessories, updated with groovy OS X animation effects.
