French street artist Astro brings an impressive sense of view to his public murals that turn flat covers into portals that seem to recede into another dimension. Already known for his wild calligraphy-inspired patterns, the artist has begun to include 3D illusions with the help of shadows to form tunnels and voids at the center of his works. Astro’s latest piece was recently created as part of the Loures Art Publica project in Loures, Portugal.
