This book is one of my thesis package that is about investigating physical aspects involved in graphic design through physical materials; thread, thermal tools, sand, mirror, and ink. There are three different steps; material version(only handcraft), digital version(only digital), and hybrid version(combine both). The letter’s reflection-shape from mirror is very flexible; it depends on the angle of the reflecting mirror. With a different perspective, the reflection-shape made different structures in the space. I created the poster that looks kind of like a sculpture of letters, showing a reflection well. You can compare how different between material and digital version processes and final outcomes. Moreover, you can touch the physical material, mirror, on hybrid version poster.
