There certainly is not a shortage of word cloud creation tools on the web. The latest that I’ve tried is WordWanderer.
WordWanderer attempts to be different from other word cloud creation tools by letting you drag and drop words to rearrange the look of your word clouds. Additionally, WordWanderer includes a search tool that you can use to find a word. The context of your chosen word is shown below the word cloud itself.
