G+7 is a sweet little Windows 7 desktop gadget which enables you to have your Google Plus feed on your desktop.
You can look at your stream and it will include everything from links to images. You can also +1 stuff straight from the gadget and view it on the web if you wish.
You change how often it refreshes but you can only login with one account.
It isn't the prettiest gadget out there but should be good enough for everyone.
