Gradation

For gradation, I used a plus structure that moves out, away for the center and in the structure I used the first letter of my name, I, as my unit form.  In this way I created a gradation structure that moves your eye gradually out.  This design creates interest through its multiple designs within a design.  The I's of course create a design but also the squares formed by the space between the I's also creates a gradating unit form in the design.
