Above: Gabrielle Tigan devised a code that involved the intervals between letters in the alphabet. She used it to send her partner encrypted letters from famously separated lovers. The project took its final form as a collection of quotations from these letters in postcard form.

Find a partner and design a code, ideally one suited for a specific purpose. Pass messages back and forth throughout the week. Bring the code, your messages, and the key to class next week.

This assignment is from the class Typographic Research.
