These artist optical illusions are beautiful and whimsical.
"Anamorphoses is a site-specific series by French street artists Ella
& Pitr, who also go by Papier Peintres, that playfully transforms
rundown spaces into colorful settings for people to pose in for a
picture. The duo adds anamorphic illusions of picture frames throughout
the space from interesting angles. Depending on one's perspective, it
can look like a person is walking inside a portrait."
