It’s a brilliant idea to tag blog post. It enables people to find information they’re looking for, but because tag clouds usually offer a more adventurous mode of navigation. If someone clicks on a tag called “water” there’s no way of telling whether he is going to end up reading about water shortages in the third world or the chemical composition of rain.

However, the way tag clouds traditionally look is boring. Enlarging the font for often-used tags causes all sorts of line height weirdness as well. This why Roy started experimenting with Flash to see if he could come up with something better looking. He has created WP-Cumulus which 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.
