In Illustrator create a file that is 4″ x 4″.
Using 1 or 2 letters, play with the space and figure ground relationship.
Use only black and white and don’t add any other elements
Try to focus on the black and white shapes that the letters make.
Don’t try to make them look like anything symbolically (like a hat, turtle or a smiley face).
Try to hide the letters so that we can’t tell what they are.
