The most diverse and species-rich ecosystem on our planet

About

vrbrille
Coral reefs are like eco-friedly megacities

Tropical coral reefs represent the most diverse and species-rich ecosystem on our planet. Unfortunately, coral reefs are highly endangered because of rising sea temperatures due to the climate crisis. The more species-rich a reef is, the richer its sound. Such a reef forms an entire symphony. Soundscape is therefore a very important characteristic of an intact reef. Young fish and coral larvae orientate themselves by this sounds when they are looking for the way to the reef to settle there. This is crucial for the survival of the reef.

Storyboard

“Imagine you are a coral larva. You were born in the reef and immediately floated out into the ocean to escape predators in the reef during your first days of life. Now you have grown a little, you are strong and powerful. And when you have reached the size of a snowflake, you are ready to conquer the world. But how the heck will you find your way home? This is not ‘Finding Dory’ and there are no friendly sea turtles to show you the way. This is the real world. You are a very small creature – lost in a very big ocean.”

Hydrophonic soundscape

The term 'riff' has two different meanings in German: In addition to ‘rock formation’, he also describes a sound figure in music.
The more diverse a reef is, the richer the sound. Such a reef forms an entire symphony. Thus, soundscape is a very important characteristic of an intact reef. Young fish and coral larvae are floated out to the open sea after birth. They orientate themselves to sound in particular. The soundscape of the reef is therefore crucial for them to find their way home.

Most people are unfamiliar with coral reef symphonies: bubbling, roaring, popping, crackling, crunching: many sea creatures produce unique sounds. If coral reefs die out, these soundscapes will also disappear. The project also invites people to listen consciously and sensitises them to soundscapes.

Virtual space of a childeren’s cave world

About

One of the basic human needs is to create a protected space around oneself, to feel secure and to shield oneself safely from the outside world.

Cave exploration

Concept

The objective was to create a childlike cave world consisting of toys and materials that children like to use. The aspects of hiding, seeking shelter, redesigning and repurposing are taken up and visualised, as well as a quest (for cats). A mysterious atmosphere is created, as well as a playful approach generated by interactions. The accessible cave can be explored and investigated. The aim is to experience childlike discovery.

Finding cats

Aesthetics

Children are particularly inventive and creative in what they do. The eternal unfinished, the constant change is characteristic. Younger children are constantly remodelling and redesigning. They are not as result-orientated as adults, the process, the play is more important than the result. I took up this aspect of imperfection by not post-processing the LIDAR scans or 3D scans. Their partially ‘broken’ and unfinished look is intentional. The architecture of the cave was a chaotic process, there is no real system, it was created a priori ‘by feeling’. Children are extremely curious and there is a lot to discover and to marvel at in a cave.

Hörweg

An Augmented Reality Project Series (Dieburg, Groß Bieberau, Schaafheim)

In coorporation with Hochschule Darmstadt and Odenwaldclub e. V. (2019–2021)

hola
Bring your headphones!

Objective

How can we raise awareness of the fact that environmental sounds have an aesthetic value and at the same time critically point to the ecological state of our natural habitats? Following the central principle of ‘Acoustic Ecology’ coined by R. Murray Schafer, it became a common goal to create something sustainable, that would engage the local community with the core ideas of Acoustic Ecology. Together, we decided to utilise a popular hiking trail to provide lasting ecological sound experiences for members of the community. The objective was, to identify conscious listening as a sound and fascinating approach that promotes understanding of the environment and its ecological problems.

Listening Path

Eleven listening stations along a popular hiking trail in the Dieburg Forest are intended to sensitise hikers / users to the acoustic value of the environment and nature and offer previously 'unheard' sounds. As active listeners, everyone contributes to protecting the forest and the environment.

„Diskriminierungen in den Daten werden vom Algorithmus also mitgelernt.“ (Zweig, 2019)

Objective

To claim more transparency in the use of AI to ensure equal treatment.

Artificial intelligence (AI) has become an area of strategic importance and an important driver of economic progress. Women must therefore be involved in the development of AI as researchers, programmers and users. While AI can offer solutions to many social challenges, it can also reinforce inequalities between women and men. Algorithms and associated machine learning can - if they are not transparent and robust enough - contribute to, repeat or reinforce gender discrimination because they are based on a particular selection of data or because the programmers may not even be aware of this (European Commission 2020).

Electric Vehicle Sound Composer

Personalise the sound of your car!

Study project for AMG (2023)

Riff 1
AMG tuning fans

About

The future belongs to electric vehicles. In contrast to combustion engines, electric motors are almost silent. The era of loud, rattling, howling and humming noises appears to be over. However, the EU claims that a sound must be emitted via the car's external loudspeakers (up to at least 20 km/h) to avoid accidents. This raises the question of how cars of the future will sound like: what if the driver could decide? In a world in which almost everything can be individualised – personalised car sound seems to be appropriate: The driver's mood, vehicle data, surroundings, time of day, road conditions, etc. can all be incorporated into the sound. What could something like this sound like?

Riff 1
Learning chords on keyboard

Research

Which kind of sound is suitable for this application? I found out that using natural sound samples are a bad idea! Also morphing those sound turned out to sound bad. Why? All sounds change their pitch and speed. This means that the sound is sometimes played faster, sometimes slower. Depending on how many kilometres per hour the simulated car is currently travelling, this is referred to as pitch bending in sound design. However, this means that sounds that are not continuous but are interrupted or change in some way sound strange and disharmonious. This is why I used sounds with constant pitch and volume like electric organ, electric piano, string instruments, synthesizer et al. Percussion or plucked instruments, for example, cannot be used as the notes fall off very quickly.

Riff 1
Driving Data

Concept

The car is understood as an instrument that changes the sound depending on parameters such as speed. The car can even be understood as an orchestra in an extended version, as chords can change, sounds re added and removed again depending on the data situation. This means that the driving data (such as speed, torque, etc.) and the user input (which sounds were selected via the interface) generate the sound.

Personal Sound Composer GUI

Objective

Users can experiment with sound and discover how sounds sound in a different context (driving situation). This offers the opportunity to deal with the topic of mobility of the future and to put people at the centre as active designers. The aim is to create an awareness of the fact that everyone makes an active contribution to shaping the environment: not just visually - but also through a medium that tends to be perceived unconsciously in this context, such as sound. What does our future sound like?

Not My Day – A Cyber-Futuristic Nightmare with a Wink

Review

Not My Day – A Cyber-Futuristic Nightmare with a Wink The comic Not My Day is a delightfully absurd and visually striking short story that captures the chaos of an average day — set in a high-tech, dystopian future. With satirical humor, sharp visual storytelling, and punchy dialogue, the comic takes us through a series of escalating frustrations, from an SOS-labeled morning coffee to an ill-timed brain update error. Visually, the comic shines with a moody, neon-lit cyberpunk aesthetic. It combines near-photorealistic environments with surreal and comical elements — like a flying cartoon pony or the brain labeled “Error 503.” The mix of intense reds and cool blues adds to the sense of disorientation and high-stakes urgency. Narratively, Not My Day cleverly mirrors our modern struggles with over-connectivity and digital overload. The characters speak in urgent commands and snarky remarks (“Don’t forget to turn your brain on again!”), highlighting the absurdity of constant synchronization and system failures. The appearance of the animated pony in an otherwise dark futuristic skyline adds an extra layer of ironic humor — a clash of childhood nostalgia and cyberpunk stress. Final Verdict: Not My Day is an entertaining, visually rich comic that blends science fiction and dark humor to poke fun at the chaos of our tech-driven lives. Perfect for fans of dystopian futures, dry wit, and overstimulated protagonists. A small, clever gem of storytelling.
