TagCanvas is a standalone library (also available as a jQuery plugin) for creating a tag cloud with the canvas element.

As Flash seemed to dominate the “tag-cloud market”, its retreat due to losing its place in the new web, has paved way for features like canvas for creating games, interactive websites, and also tag clouds like these.

TagCanvas is a fully-animated tag cloud that also supports images as elements. What’s more, it’s supported even in IE<8, hence it employs the explorercanvas library.
