Some images flicker.
Like a never-ending disappearing act, they flicker, switching appearance over and over again, depending on how we perceive them.
Scott Kim’s True/False ambigram is one illusion that plays with the viewer’s perception. While there is a constant conflict between literal meanings, visually, neither can exist without the other, eternally embedded within the same structure.
True is embedded within false. False always contains True. Metapictures thrive on such paradoxes.
If the illusion of these images depends on how we look at them, and the multistable shift of visual and verbal meanings occurs within our own minds, than maybe they are watching us too, watching us as we realize we are just as unstable and ever-shifting. And sometimes, we flicker.
