Artist Li Hongbo, whose flexible paper sculptures we’ve admired many times here on Colossal, recently created a new series of silhouette artworks as part of a solo show at Contemporary by Angela Li in Hong Kong. Each piece is delicately cut from the knife leaving a complementary negative space from which it appears to rise. Hongbo says the pieces are meant as a warning, that “human beings will eventually destroy themselves because of their gluttony and their abuse of animals.” If you liked this technique, also check out paper sculptures by Peter Callesen.
