I recently installed some gadget sidebars onto both of my PCs:
For my Windows 7 netbook I installed the Windows 7 sidebar gadget: http://nes.bplaced.net/sidebar7.html
The install was very easy, just follow the instructions on the gadget’s website.
For my Fedora 14 Linux notebook I installed Google Gadgets for Linux: http://code.google.com/p/google-gadgets-for-linux/
See my earlier post about Google Gadgets for Linux here: http://blog.isaacmedia.net/2011/01/google-gadgets-for-linux/
To install get the google repository: http://www.google.com/linuxrepositories/yum.html
And run as root:
To start Google Gadgets for Linux (with sidebar) run the command:
Or click Google Gadgets (GTK) under Internet in the main menu
I also suggest running compiz, as compiz provides nice transparency for the gadgets. Otherwise you get ugly gray boxes around all the gadgets.
