It's all "very" 3D, because it is real... xD It's a house in Netherlands, I read the comments under the video. Maybe he used some kind of program to set timings to all the motors, lights, sounds. I have no idea what kind of pragram could do that though, maybe he just made a circuit or a set of them, that trigger all the motors, etc.
