Technology has advanced to the point where you can step into a photobooth and pose for a photo with your oshi's 3D model, and she can sign the photo and it will be developed and handed to you. This event was apparently called OshiSnap, I heard the name a few times but they didn't do a good job of advertising what it was because I thought it was just another meet & greet event (which is still nice but they're very prolific now)
