A confessional box at Walden Festival 2026 where visitors confess their sins to a local AI priest, who grants absolution - and forwards the sins, anonymized and retold in an angel’s voice, to the Holy Toilet.

This year, our Walden floor at Zugvögel became Santo Nido: a church dedicated to a phoenix sect. Stained-glass windows, holy birds, an AI confessional, and a tower-clock that goes wild with the music. A lot of religious nonsense, and so much love for detail.

This year, our Walden Floor transformed into the PetroLoco gas station that has been the site of a battle between the oil oligarchs and the ecological fraction. Next to the floor and the usual interactive installations, you could also play real-life Tuxkart here.

An interactive, networked spaceship you can actually board: players complete (or sabotage) missions across a dozen physical interfaces - buttons, joysticks, LED boards, sensors, etc - to either launch the ship or doom it, with everything driven by a Python/ESP/Unity stack. It’s modular, auto-resets regularly, and scales to festival crowds without manual babysitting.

In this (german-language) episode of Code for Thought, Carina and I discuss how large language models can realistically support Research Software Engineering - from paper-code matching to a sober look at tool evaluation, limits, and hype vs. practice.

In 2024, for our Walden Floor at Zugvögel Festival, the visitor was immerged into the crash site of an alien spaceship, featuring multiple interactive installations next to our usual dancefloor.

Having learned my ways on Theseus’ Anet A8 and now running a boringly reliable Bambu P1S, I use 3D printing and self-taught CAD as basic infrastructure for most of my hardware projects, some of which are listed here.

For the last three years I’ve been part of the crew behind Fusion Festivals largest Floor: Palapa — a collectively built, ever-changing “city of the future” and dance floor. We turn a 1,200 m² tent into a dense skyline of handmade structures, layered light, and countless small details.

An automated self-checkout system that recognizes meals on canteen trays using an iPad and cutting-edge machine learning. In my 2.5 years at this company, I helped making the prototype a full-fledged widely used product.

For this thesis, I created a Conceptual Space from Course Descriptions for explainable Recommendation, in a highly performant pipeline on the university-grid.

In this student research job for the Red Hen Lab, I worked on a pipeline that automatically detects hand gestures in large datasets of videos, involving OpenPose for Pose Recognition, Person detection, Person tracking, Scene detection and more, and deployed it on a HPC using Snakemake and Singularity to create a multimodal communication corpus from the Ellen DeGeneres show.

A comprehensive course, with lectures and interactive assignments, about Scientific Programming in Python, offered for three years at the University of Osnabrück.

Bomberperson is a maze-based multiplayer for 2 - 4 Players, that was programmed in a C++-project following up the respective university-course. All players should try to eliminate each other and be the last one standing. Player can place bombs which explode after a certain amount of time in multiple directions and can destroy obstacles and other players. Destroyed obstacles can drop power-upgrades that temporarily improve a Player.

Delving into the realm of self-driving cars for my bachelor’s thesis, I endeavored to optimize their tactical decisions, particularly speed, using cutting-edge deep neural networks and reinforcement learning in tensorflow within a transformed racing simulation. The resulting research platform, built on Unity, showcased the potential of real-time feedback and adaptability, offering valuable insights into the future integration of reinforcement learning in self-driving cars.

In this 3D-Browser-Game developed in a computergraphics-project using THREE.js, the player is trapped in the infamous burning AVZ and must try to escape this inferno. The player controls the in-game character and must overcome obstacles, puzzles and traps to get to the bottom and out of the AVZ. Play here!
