First plugin from my picture blog (now out) is the Strip Calendar. Basically a normal WordPress calendar - only not as a block for the sidebar, but as a strip to place it over the content. Since you usually have more space to waste in the length of a page than in the width and since someone might want to break with the rather worn-out format where the calendar is in a sidebar, you can now simply install the strip calendar. The code for installation is trivial:
< ?php get_strip_calendar(); ?> ```
Just put this in the header.php or wherever you want the calendar. Done (of course first unpack the plugin to wp-content/plugins/ and activate it in the administration!).
