Within the list of the best WP widgets is a widget that displays the tags of posts in a way that the more popular posts are displayed in larger font size than the less popular ones. It is called the tag cloud. There is an option for an animated tag cloud widget that makes the cloud appear to be moving. This is probably among the best WP widgets as it looks very attractive and is also very useful for users to find the most popular posts in a blog or site. It also makes it easier for users to find what they want as the tags are displayed and linked to the appropriate post.
What can you customise? The short answer is "everything". I usually work from the top down. You can design your own header graphic and upload one or more - the Atahualpa theme has a built-in header rotating function if you want to use it. You can have an area above the header graphic (or below it) for your company logo, RSS and comments feed and a search box. You can style this area to blend into the outer background or you can give it a style of its own and make it stand out.
