Geometric Patterns Sample Sheet ZJ

Introduction:
  These patterns are created by using Adobe Illustrator. I simply just created some simple lines and find their center point by pressing 'R', drag the image with 'alt', then press 'control+D' to make a continuing rotate pattern cycle. Some of the patterns I repeated by double click the Selection Tool and change the height and length of the image and use 'control+D' to finish repeating the pattern.
