Here is my abstract art piece made in Adobe Illustrator.  I used the letters "J" "A" and "M", playing with the borders, strokes, and colors to create the above images.  I really liked the contrast between the vibrant colors and the block font, so I created the jagged "etchy" strokes on the edges to add some depth.  I also used the eraser, rectangle shape, clipping mask, and border tools to complete this project.
