Sergi Cadenas is a self-taught Spanish painter whose oil paintings show two different images, depending on where the viewer stands. Walk past one of his portraits from left to right and Marilyn Monroe turns into Albert Einstein, or a young woman ages by decades.
How the paintings work
Cadenas uses a piping bag of the kind made for decorating cakes to lay thick vertical ridges of paste across the canvas. Once they have set, he paints one image on the faces of the ridges that point one way, and a second image on the faces that point the other way. From the front, the two images mix. From each side, only one is visible.
He has said the idea came from flip images on cards he saw as a child. He did not start working as an artist until his 30s, My Modern Met reported.
The subjects
Many of the pairings deal with opposites: youth and old age, life and death, one emotion and its reverse, and skin colour. Others show the same scene from two angles.
