Materials used: several types of metallic silver paint, foam brush, metal parts and bolts from hardware store, used bicycle gears, used car part from a junk yard, letterforms cut from black board
The background of the poster is a scrap piece of copper that I urinated on to patina it. Free and easy solution!
I played with different ways to integrate my letterforms with the metal and scrap parts and then photographed them from different angles on the copper background.
My two favorites are pictured below.
