Clean modern book cover. The main starting point here was to learn about the agile methodology.

So, since agile is a continuous cyclic process, and the client said this is first book in a series, I thought that I should go to basic elements and maybe use a circle as a main graphic; continuing with other basic elements on the other books. So, I was thinking that a circle, defines best the agile process. But I realized that something is missing. The circle does not imply movement, dynamism, and agile is dynamic. So, I imagined the circle moving in an upward direction (evolving, growing). But then again, I thought that agile implies teams rather than individuals, so I added another faded line. This is how i got to this.
