This Illustrator tutorial guides you to create a "Geometric Background" with the Polygon tool. We will start with the polygon tool and create some shapes with the pen tool using guides. Use shadow on the corners and back of each shape, to make a depth and 3d feel on the object. This graphic looks typical but it's very easy to create, Watch the tutorial till the end and follow the steps, you'll love it, at the end of the tutorial I make some other color combinations, with the same color and also in different color shades. Thanks. Deep Tuts video.
