Here is my entry for Illustration Friday theme which is Black & White. I was inspired by Zuzana Licko of Emigre Fonts who developed Hypnopaedia. Notice the concentric rotation of a single letterform. When repeated, you can have a unique pattern of interlocking lettershapes. There are infinite possibilities. I created my Black and White image using rubber stamp letters and numbers. It was quite a challenge lining each stamped letter to be in the correct position.
