WP-Cumulus
顯示標籤雲的外掛3D FLASH版
WP-Cumulus allows you to display your site’s tags, categories or both using a Flash movie that rotates them in 3D. It works just like a regular tags cloud, but is more visually exciting. Clicking the tags can be a little hard (depending on your speed setting) but does take you to the appropriate page
