== DESCRIPTION:

Generates pdf-files with word clouds based on input. Inspired by wordle, but probably uses an entirely different algorithm, since Wordle is not Open Source. Also:

* Outputs only in pdf (if there was a decend svg writer for ruby, I'd use that). 
* Can't put words inside other words like wordle, and also a big word has a big space surrounding it while a small word has a small space.

But it is open source so feel free and encouraged to hack away and make this gem better.

The algortihm is a bin-packing algorithm. This means that clouds aim to take up as small an area as possible. A word has a surrounding box and that box is placed as close to the "center" as possible, where is does not collide with other boxes. The "center" is computed by a radial function, of which I have implemented several, making is possible to generate clouds of different shapes.

This is a beta in the original sense of the word, not in the google sense.

My blog-post introducing "cloud" is here: http://ninajansen.dk/2009/04/23/introducing-cloud-an-open-source-ruby-wordcloud-generator/

If you have used cloud to generate a cool wordcloud, please upload it to scribd and tag it with "wordcloud". Documents with this tag are here: http://www.scribd.com/tag/wordcloud 

== FEATURES/PROBLEMS:

* Can generate a word cloud from text, rss-feed or del.icio.us name
* Can use a number of different color palettes
* Can use a number of cloud shapes
* Can ignore common English and Danish words (feel free to add your own language(s))
