Wonderbra, or their ad agency, has an taken a innovative approach to draw attention to their product. It’s this:

It’s a billboard/photograph made of many women of all shapes, sizes, and backgrounds in their…well, the same thing wonderbra sells. 🙂
The same technique could be applied to anything, and I wouldn’t be surprised to see this used for other ads as well.
More details on the campaign can be found here at 3MakeStuff Blog on World’s greatest collage?
Oh, with a few exceptions, it’s likely NSFW.
OK… first it’s kinda cool for a billboard but kinda stupid for a website.
Second.. what on earth is the viral component in this ?
