Vector Graphic Patterns

I have been spending a lot of time in Adobe Illustrator lately. There is something exciting about vector design, and perhaps it is the geek in me that enjoys working with geometry and numbers. That said, flat graphics can get a little boring, and so I have been enjoying the use of simple gradients to trick the eye into thinking a scene has depth… Interesting how such a complex three-dimensional pattern can be achieved with only a few simple clicks in Illustrator.
