Despite their inherent stillness, the letterforms' scattered contours evoke a constant vibration. At a smaller size (or heavier weight), the particles congeal into solid strokes with irregularieties reminiscent of handwriting.
Tinnitus is a condition when a person hears a ringing or some other variety of sounds when no corresponding external sound is present. The word tinnitus comes from the Latin tinnire, “to ring”. It is common, affecting about 10–15% of people. Most tolerate it well, and it is a significant (severe) problem in only 1-2% of people. Rather than a disease, tinnitus is a symptom that may result from a variety of underlying causes; the sensation of it may be generated from any stage in a person's auditory system or even outside that system.
