With randomized images http://jsfiddle.net/TfQ2y/embedded/result/

Very cool! :) Can you filter the punctuation marks? It shows broken images for things like question marks and periods.

Unfortunately, escaped characters aren't allowed as subdomains so you'll have to hardcode them as a switch/ifelse chain which returns appropriate searches (eg . => "fullstop.jpg.to")..

Feel free to fork and do so though :)
