We’ve heard of cookies on your computer but this is a little different. at the South by Southwest Festival in Austin, Texas, people are standing in long lines to create and print out actual 3-D Oreo cookies on a 3-D printer. We didn’t know you could use that for food. This sounds very Willy Wonka to us! Actually it looks like the cookie part is already made and the cream filling is squirted on. But it’s still pretty neat!
