I’m always looking for new and novel ways to incorporate technology into creative. Google is on the same wavelength. Their creative laps are constantly coming out with new ways to utilize technolgy they develop. In this case they have linked a database of thousands of pose images to the users camera so when you move, a matching pose appears. What is it good for? Who knows, but it’s a tool that can now be added to your arsenal.
