Google announced on Wednesday that it is adding Google Gadget support to its Google Desktop application for the Mac. Google Gadgets are similar to Apple’s Dashboard widgets, but are cross-platform and work in Dashboard, iGoogle pages, and the Google Desktop Sidebar. 
Google Desktop: Now with Gadgets
An extensive list of Google Gadgets is already available, and like their Dashboard widget counterparts, can gather data from the Internet, track stocks and weather, display blogs and news feeds, and more.
The updated version of Google Desktop for the Mac with Google Gadget support should be available as a free download some time on Thursday.
