I am playing around with a website that I can think of many educational uses for-- Wordle. Wordle is a free word cloud generator, and it's creative potential is endless. You can do cool random changes of whatever text you type or paste in, then print the results, or use it in your blog or on your webpage. I am sending this out to our English department, and art department. I am also picturing using it to make signs for the library--make one for the 600s, using words that are represented in that Dewey section. For example:
title="Wordle: The 200s Dewey Decimal System"> src="http://wordle.net/thumb/wrdl/190370/The_200s_Dewey_Decimal_System"
