Little Caesars' floating heads return in a Facebook Canvas campaign for the brand, encouraging users to press buttons for "surprises," and leading them through a series of multimedia interactions.

Facebook recently held a "Canvas Hackathon" for agencies and marketers and the campaign, by Barton F. Graf, evolved from that. In the brand's typically teasing style, the interactive experience tempts users in with a big button marked "Do Not Press." Users can then tilt and swipe the screen to see the floating heads in more and more quirky and hilarious styles.
