yahoo voodoo

my company got a deal to run a yahoo ad campaign using a flash banner that would let you put some text into a text box and submit it to a search on their site. but they did it in the most convoluted and cryptic way -- all to make sure that they could track clicks on the ad etc. for the technically inclined, the setup is using flash to call javascript that writes it's own vbscript AND more javascript... it's voodoo i tell you.
