In 1994, I began to design simple, two-dimensional interactive typographic pieces of a computational nature. Many of the technical pieces that I had kept unpublished for years, such as physical simulation and an assortment of visualization techniques, came together in another Reactive Book: a collection of 10 works rendered in monochrome. Again attempting to meld the digital and print traditions, I wrote and illustrated a small story about the evolution of Flying Letters to complement the digital media.
