Typically, in a professional project, the embeds are not forged out of pure text. Rather, they are blended as a piece of scenery (though text is often the case but with types of fonts I don't have.) An example would be in Cinderella. About 1/2 way into the film, the Prince's men come calling to Cinderella's house. Behind the men, as the door is opened, is a fence way in the background (an Iron fence) Well, the curls of the fence clearly make out the word sex, but chances are you never saw it because it's off-center and not the main subject of the screen. A text example would be a cardboard "standee" of Barney the Dinosaur I once had the privilage of seeing every day at work. If you got in close and studied the felt texture of Barney's felt costume, you could see the word sex made up the texture in all different sizes. Playboy likes to hide the word in Model's hair. McDonalds likes to put it onto a picture of a cheeseburger in newspaper coupons (along with all kinds of death imagery (skulls and stuff). Alcohol ads...oh my god. All kinds of things can be seen swirling around in a alchohol ad. (even more)
