"Blow Your Mind" is a typography project attempted to produce letters that interact with users. The project, which started with letters that vary in form according to sound by selecting a microphone as an input tool, expanded the range of noise-wind sound-log input created by users, as well as voice, to induce actions other than just speaking. Developed in the order of "SHHHH," "Blow 1," and "Blow 2," the project contains a process from transforming the shape of letters to revealing flowers consisting of letters.
