This Ad for Snickers Candy Bars Surprises with Facial Recognition Tech

Super Bowl viewers from this year will be familiar with the commercial for Snickers candy bars that aired during the game featuring the beautiful Marilyn Monroe transform into Willem Dafoe to remind audiences that 'You're Not You When You're Hungry.'

This ongoing campaign continues with a billboard from Snickers that features an iconic moving image of Monroe. With a built-in camera and facial recognition technology, this billboard catches people staring and quickly swaps the face of the blonde beauty for Dafoe, who offers cranky quips about standing in heels and more.

This is one of few billboards that people on the streets seem to be elated to engage with, even if they know what is coming.
