Opzao? Opzao is lines, shapes and color. A gallery of vector images. My name is Massimo Montagner and I want introduce you on one of my passion: the vector art! When I begin to use a computer I discovered the world of vector graphics. Now I'm a software developer but I kept my passion for this way of design and I want to share it with you. All the images are free downloadable. Welcome to OPZAO!
