One of the last things I do when finishing off a new website is to create a favicon.
Favicons (favourite icons) are the little graphics that you see in the address bars of modern browsers, they also appear next to bookmarked websites which can be helpful when trying to find a particular site in a list of others.
Thanks to online favicon makers they are simple to create from existing website logos and graphics.
Though their size 16×16 can be limiting it is surprising how creative some people mange to be, there are some good examples in this favicon gallery.
Here are some more favicon links -
