This is a website that uses a Java applet to generate rather artistic word clouds with ease. You can either type/copy and paste text or pull text from a website to give the generator a word set. Then it will take that word set and create a random word cloud, which you can customize by changing colors, fonts and layout. The best way to understand what it does is to try it for yourself.

Here is a link to one that I generated from the text on this blog.

Try it out for yourself at the link below.
