So as I was looking for ads with illusions I found this one. This is an ad that veja created and first you might see the giant letters that say suicide but if you look in-between the lines you can see that it says right to die. This is a figure-ground ambiguity illusion because one can see two different interpretations depending on whether you see the “suicide” or the “right to die”. Part of seeing this is that if you focus on the black or the yellow in the ad. I liked this ad because if you look in the right bottom corner you can see that it says “Get both sides” and this ad is puny because when you truly look between the lines of suicide one can understand that it is one’s right to die.

Figure-ground ambiguity is the illusions in the notes about the candle/faces and the cup/faces. This illusion uses top-down processing because as the notes say, “…we see in an ambiguous figure can be altered by priming”.
