Calligraphic Optical Illusion Murals by Astro French street artist Astro brings an interesting sense of perspective to his public murals that turn flat surfaces into portals that appear to recede into another dimension. Already known for his wild calligraphy-inspired patterns, the artist has begun to incorporate 3D illusions with the help of shadows to create tunnels and voids at the center of his works. Astro’s latest piece was recently completed as part of the Loures Art Publica project in Loures, Portugal. You can see more of his work on Instagram.
