This adorable little girl in the pink dress is not starring in an advertisement for Barbie, Disney, or even a PSA aimed at parents who dress their children in ridiculous pink dresses. It's actually an ad about something far more sinister, but it does make awesome use of glow-in-the-dark technology.

Brazilians might see this ad from the country's organization CERCA, which fights child abuse.

"A unique print campaign printed with fluorescent ink, which glows in the dark. With the lights on, you see one image. When the lights are off, a new image will appear."

It's the same neat trick Vice magazine used to promote the BMW 1-Series.

Except, you know, instead of raising awareness about a hot new sports car, it's about feeling up little kids.
