Read the article about the commercial too.

 

I saw that before, very funny. I like the wiper blades going across the floor! How come they couldn't do this for the S2K? Thanks for sharing again, I can always watch that video!

 

that is just crazy, and I have to not beleive it was not edited in some form. Some of the movements were not looking very natural, like the wheels going up specially that last one. Great commercial, just had to be digitaly edited.

 

There is an article floating around the boards about the making of the film. Apparently the wheels were made to work by filling them with nuts and bolts to give them some momentum. Do a search for "cog commercial" and you'll find the post with the article.

 

The wheels had weights in them. With the weights mounted inside the tire, up top, you could balance them so that a slight push would cause them to roll up hill.
