Here (opens in new window) is a page with a link to Honda's new commercial, titled "cog". It's 2 minutes long, and worth every second.
In short, they took parts from the new accord (ugly ass car) and made them go through a set in a sortof dominoes style, each piece bumping up against the next. All done for real, nothing computer-generated. It took them 606 takes before it finally worked right.
You'll need shockwave to view it.
