Created by Jonathan Feinberg, Wordle is a web application running on Google’s infrastructure that generates word clouds from text you provide.

Very easy to use, you can play tweak almost everything from the fonts, the layout to the colours in order to design your own colourful word collages.

You can’t directly save a picture, so stretch the window to get the most of your resolution screen then you just have to grab a screenshot et voilà!

Those visualizations have been generated using the rss feed of this very blog + quick retouching (texture & light).
