The first is a video of a folded unicorn, quite complex. The second is of a folded dragon, even more complex. Third, the first half of a demonstration of folding a unicorn and then the second half. A brief clip showing various unicorns, supposedly replicating the unicorn in the movie, which is less detailed than the one in the demonstration, and finally, the unicorn dream which some viewers feel Gaff is hinting at when he leaves the unicorn and which might imply that Blade Runner's main character, Deckart, is a replicant, too. On the other hand, it might mean that he knows Rachel is with Deckart and choses to give her a chance to escape. Annnnnd, probably what you're looking for, the real origami unicorn from the movie, which is a bit of a cheat since it uses three pieces of paper, plus glue.
