With the instructions below, you can put a Grazr on your Google Homepage. But with my latest little chunk of code, the OPML Cow Contraption, it lets you easily make a link that lets you put your own OPML and setup on to other people's Google homepage. 
The Cow Contraption needs three pieces of information to work. 
First of all, it needs an OPML file (defaults to my directory). 
Secondly, it needs the height in pixels for the Grazr (defaults to 400). 
Thirdly, it needs the title for the gadget (defaults to "Grazr"). 
If you have those, you can proceed and build yourself a link. 
You can use this to fine-tune your own Grazr gadget or use it to promote your own outlines (people can always change the outline and title though).
