When you submit a phrase, the Image Writer repeatedly queries Google's image search and spells out your phrase in pictures, using one the first search result for each word in your phrase. The result is a coded representation of your text, based upon Google's best approximation of the overall opinion of the web at the time of your search. Hold your mouse over each image to see the corresponding word in your phrase or click an image to see it in its original context.
