Beautiful example how to forge technology into ART. Rythm of the Lines is the promotional site of new Audi A5. Excellent example of use Papervision3D. User can create his own piece of art on-line using keyboard. He can create mood by creating lines, change camera angles etc. All created works has ambient sound mood making this site one of the best examples how to create something and advertise product in non-straight way. Highly recommended.
