Mathematica now has a nifty feature that allows you to create "word clouds" from various on line data sources such as wikipedia. So here is tiny bit of code to do this.
words = DeleteStopwords[WikipediaData["Analytics"]];
OK that was easy now lets try "White Pine";
Of course you can change the orientation and even make it random. Another thing you can do is make the outline of the word cloud conform to another image like this:
Maybe not the best outline shape...
