This project investigates toilet wall writings (known as Latrinalia) as a form of anonymous communication and unfiltered creative expression within an art institution. Originating from an interest in graffiti, stickers, and walls as communicative surfaces, the project began with an observation: while many institutional spaces are visually controlled and neutral, the toilet walls at the University of Arts Bremen appeared dense with messages, marks, and voices. What might fade into the background for those familiar with the space revealed itself as an alternative archive of expression.

 A quote encountered there became a conceptual trigger: “Since writing on a toilet wall is done neither for critical acclaim nor financial reward, it is the purest form of art.” This idea prompted an investigation into whether these uncommissioned, ungraded writings could be understood as a form of art created free from institutional pressure, evaluation, and expectation. Rather than framing them as acts of vandalism or rebellion, the project considers them as spontaneous acts of creative expression.

Importantly, this project does not attempt to define what art truly is. Instead, it focuses on the power of declaring something as art and the freedom inherent in that act. By paying attention to what is usually ignored or erased, the project questions who has the authority to assign value and meaning within artistic and design contexts. The act of naming these writings as art becomes a subtle challenge to institutional norms.

Public toilets are central to this inquiry because of their spatial contradiction. They are public spaces entered for privacy, places where individuals can momentarily withdraw while remaining within a shared environment. In this tension between public and private, anonymous communication emerges. People write while unseen, leaving traces for unknown others. Latrinalia transforms these functional spaces into organic, evolving surfaces shaped by collective participation. Across these walls, a recurring message appears: “I was here. I exist. I matter.”

By documenting, scanning, and enlarging, re-presenting these messages, the project aims to amplify voices that are usually ignored or erased. It does not seek to analyze or categorize them, but to let them exist more visibly in public space. Layered, messy, and imperfect, these writings mirror the structure of communities themselves.

Pomus is a creative production studio known for strong storytelling, striking video work, and bold direction. Sömestr worked with Pomus to build a new brand identity for its next chapter, focused on attracting global talent and clients.

The design uses variable typography and energetic layouts inspired by movie title cards. The Pomus logo has six versions based on popular film genres, adding variety and character across communication materials. It was produced as a .OTF font (with Element Type) for flexible use and animation.

We also created a custom typeface, Pranklin Pothic, inspired by Morris Fuller Benton, to extend the typographic style across the website and other designs. The result is a colorful and powerful identity that reflects Pomus’s mission: telling stories that move people and leave a lasting impact.

The diverse backgrounds and cultures represented within the Integrated Design Master program, we opted for a typographic system that could easily adapt and evolve. We amalgamated various letter designs, symbolizing our individuality while emphasizing our collective identity.

One of the most remarkable aspects of the MAPOOL Display we designed is its inherent connection to a community and its ability to deliver meaning from the community's existence. In this Master's program, people will continually come and go, and this fluidity is fundamental. Consequently, our typeface reflects this essence. Even after ten years, new students can modify our letters, sketch their own combinations on paper, and digitalize them. Thus, our typeface evolves, ensuring its continued relevance and vitality within the community. 

This adaptability underscores the living nature of our typeface. In developing our letter set, our primary focus was on maintaining a diverse range of letters, encompassing various forms such as boldness, thickness, serif, sans-serif, organic shapes, and geometric designs. This diversity ensures the versatility of our typeface, allowing it to adapt to different contexts and express a wide range of messages. Subsequently, we proceeded to combine various letters and assess their cohesion.  A kinetic brand identity entails maintaining a cohesive identity without relying on a static logo.

Poster Design


This experimental poster selection showcases my approach to pushing creative boundaries through bold typography, unconventional layouts, and expressive visual systems. Each poster is a space for exploration, where I test ideas around color, form, and composition without the constraints of commercial briefs. The collection reflects my design process, focusing on concept-driven visuals and intuitive experimentation. Through these works, I aim to challenge traditional graphic structures while maintaining strong visual impact. This selection represents my ongoing exploration of graphic design as both communication and artistic expression.
