Snapchat's new world lenses are its biggest push into augmented reality

Snap Inc. is a camera company, and on the day of F8, Facebook's annual conference for developers, they want to remind the tech industry, Wall Street, and their loyal users of that mission. 

Snapchat is launching new world lenses, an expansion of its world lens feature (released just ahead of Spectacles in November) that puts animated objects like vomiting rainbow clouds in the real world, as seen through your smartphone. The big change is that these lenses (and the images in them) move and change as you move, making them slightly interactive.
