This ad by Honda is amazing. None of what you see is computer generated. It all happened in real time. The ad, titled “Cog”, consists of 85 car parts and took 606 takes. And yes, they are all real parts from a Honda Accord.
And here’s the same ad on the Honda UK website. Click on “Honda TV”, then “Watch our Adverts” and then click “Cog”. There’s also a “Making of…” video.
