Random design I did for class

(after the jump)

 

This is an exercise with Adobe Illustrator where you 

pick two or more letters

arrange them in some pattern so that the pattern is too large to fit on a 3x3 art board

Crop the pattern so as to put it on a 3x3 artboard

Create another 3x3 art board with the same pattern but with inverted colors

create a pattern on a 9x9 template with those two 3x3 art boards
