Sculptor Manuel Martí Moreno lives and works in Valencia, Spain and forms these wonderful figurative pieces out of iron nuts. Via email Moreno says that he is most interested in showing the passage of time, the transience of life, and our collective awareness of our own mortality, seemingly evidenced by the spectre of decay at the edges of his works. You can see more images including installation shots on his blog, and also here. If you liked this, also check out the sculptures of Park Chan-Girl. Thanks Manuel for sharing your work with Colossal!
