Geometric patterns, inspired by the low-poly look, have become a growing trend in that last couple months. They can be used for website backgrounds, illustrations and posters. They provide a great way to break away from the standard flat design backgrounds to something more abstract.
All 3 backgrounds come in both .AI and .JPG formats. In illustrator you can fully edit any geometric background to any way you like. You can change each triangle color and re-size the background to meet your exact needs. The JPG versions come in high definition (300 dpi) at size 2500 x 2500 px. This allows you to use these geometric backgrounds in a variety of design projects.
