Wordle is a fun little web site that lets you create art out of words.  It was created by an IBM software engineer named Jonathan Feinberg.  You can view other users’ tag clouds in the gallery or easily create your own based on a block of text, an RSS feed, or delicious bookmarks.  Then you tweak the appearance of the cloud by changing font, layout and colours.  The image above is constructed from mediakik’s delicious bookmarks.
