Lookey Help

Has anyone identified the Lookeys in the film? I've used the Lookey symbol sheet (http://www.spotthelookey.nl/lookey/) and I've spotted some of these symbols in the film, but they weren't out of place, as the Lookey game has been pitched. I'm wondering if the symbol sheet is some sort of decoding system that corresponds to discontinuities in the film. I'm also wondering if the Danish release version, where the Lookey contest was held, is different from the US release. Any info or Lookey answers would be much appreciated.
