Filter By Category links

I was wondering if there is any way to filter the categories by listing links rather than the drop-down box? For the project I’m working on now it would be more aesthetically pleasing if the user could click on the actual category title rather than showing a drop-down box. Even if you could provide the PHP code that would create the link to show the appropriate category would be great and then I could just pop it into my WordPress template. Is that possible?
