This is an old one, over a year, but while in the office someone was playing with those optical images that put images onto your eyes that you see when you close your eyes. Reminded me of this that I found ages ago, I don’t think I’ve put it on here so I thought i’d post it now! BMW used subliminal advertising trick to ‘burn’ an image onto the eyeballs of a whole room of cinema goers. They did a whole load of set up for it to work but the end effect was great. The advert, for BMW motorcycles, flashed the company’s logo onto the screen for a period of time too short to be seen, but for long enough to register on the watchers’ eyeballs. At the end of the advert, the audience was asked to close their eyes, whereupon they should have seen the faint image of the BMW logo for a few moments before it faded away.
The video below shows how they did it and the advert itself, though unfortunately the projection won’t work on you through this video!
