Blog widget & Bookmarklet with "uniqlo lucky switch" logic

Hi, I would like to develop same service as "Uniqlo Lucky Switch" project. I need JS experts to develop similar to "Uniqlo Luck Switch" logic to change page content. 1) bookmarklet 2) blog widget (so users can embed in their own website) please see the following link with demo movie. server side is NOT needed - I will develop !!! I need JS expert that will develop the scripts that will replace all images / flash_movies and put my content instead. the existing page content URLs should be replaced with dynamic links to Flash SWF on my server that will include the following information: 1) original content URL (e.g. URL to original image or to original SWF that it is replacing) 2) size (e.g. w=200&h=300) 3) any other info available the code should be working on any website so to test it, please go to YouTube for example and see that all movies & images are replaced. regards, Gilad
