Google Gadgets are little widgets that add more features or functionality to a web site, Google application, iGoogle and other platforms. What Are Google Gadgets and Their Uses? explains what they are and how you can put them to work.
If you use Google Calendar, you can add a small version of the calendar to your web page, Gmail sidebar or elsewhere by copying the URL when you click on "View Source." If "View Source" isn't available, you can look at the URL for the gadget and copy / paste the second URL (the bolded part in the below example):
http://www.google.com/ig/directory?type=gadgets&url=www.google.com/ig/modules/colorjunction.xml
However, Gmail has the Calendar Gadget available in Labs under "Settlings," so you don't need to grab the URL for the gadget. Some other gadgets are available under there, too.
Google Gadgets aren't limited to tools that help you in your work and life. They also include games, horoscopes and time wasters. The following best Google Gadgets pick the ones with the most users and best ratings.
