Here's how you do product demos right: Advertising firm BBH has produced a series of videos for the Google Chrome browser, and you have to give them credit for creating such intuitive, almost naive metaphors for a very unemotional "technocratic" brand. Since Peter Greenaway, no one has married math and artistic expression more convincingly. It's truly "A New Way to See the Internet."
From the BBH labs site: "We took Google’s ingenuity & innovation as inspiration in developing the idea for seven short films (& an intro), demonstrating the benefits of Google Chrome. Every creation is built by hand, filmed in camera, with no special effects added. Even the music has Jacqui, the harpist, playing live on set. As it should always be with Google, the product is the hero. We celebrate the Chrome product, but we hope in a "Googley" way."
