This is a fun one, create a tag cloud from a list of words, which you can also use as a menu.
There are 9 weights which correspond to the 9 font weights available, although not all fonts provide 9 weights. The one I've used as default has 5.
Customizable as much as possible, you can add colors for each weight, set a minimum count to achieve before an item is shown, and quite a bit more.
The actual cloud is created in HTML on a webview.

Version: 0.9
The attached demo is quite large as it has a 10,000+ word list that it builds the cloud from.
When you create a new project with Tagcloud, you'll need to load the fonts into your files tab.
This is definitely a beta library. Copy the jar and xml files to your addl libs folder.
Currrent Version is 0.92
If you are using the V3 Beta3+ please download SLTagCloud-3Beta3+.zip, otherwise download SLTagCloudLibs.zip.
