Here is another version of a JavaScript prompt that can allow your visitor to change the
                            background color of your Web site, on mouseover, if you use a solid color background:

                            <a href="" onMouseOver="var bg=prompt('What color would you
                            like?');document.bgColor=bg">Put your cursor over this link to change background
                            color!</a>

                            Because of my tables, this example won't work here, but you can see what the prompt
                            looks like =)

                            Put your cursor over this link to change background color!
