WP-Cirrus is a plugin that displays a 3D tag cloud in your WordPress. It can be 
used as a widget or anywhere on your blog using the [wp-cirrus] code.
WP-Cirrus was inspired by the famous WP-Cumulus plugin. WP-Cirrus uses no Flash, 
but only JavaScript and CSS to display the cloud. It gets all meta tags directly 
from WordPress.
Our plugin makes no use of external libraries that have to be loaded with it at runtime 
(e.g. jQuery or even Flash). This makes it very small and fast to load.
As it’s still under development more releases will be seen in near future.
Have fun and tell us what you think about it.
