YouTube - dove evolution
Check out the video link above from Dove corporation, and you will never look at a billboard or magazine cover of a "beautiful" woman the same way again.
Also, see a similar treatment that was given to one of my favorite Tech bloggers, Amber Macarthur. Can we all agree that Amber is a nice normal looking woman who doesn't need to be turned into a weird cardboard cutout?
