What if you could design and print your own Oreo cream filling, with a selection of possible flavors? At SXSW, people can do just that at Oreo’s Trending Vending machines.

Users pick a trending topic on Twitter and get a cream-filled cookie inspired by that topic. The entire process happens right before their eyes as a turret of flavored fillings pumps cream onto the cookie, which is held by an inverted delta robot. And what’s cooler than a machine that creates custom Oreo cookies on-demand? Seeing how it all works inside.

Check out the video above to get a tour of the many different technologies come together to create this unconventional vending machine.
