An Evil Kryptonian in a Pleated Skirt

Superman's Brainwashed Stint as a Warrior of Apokolips

In March 1987, John Byrne, Marv Wolfman, and Jerry Ordway ran one story straight through all three Superman titles: Darkseid abducts the Man of Steel, burns away his memory, and remakes him as the loyal son of Apokolips. A close reading of the three issues, the philosophy they smuggle in about identity and free will, and the ripples they left in the Superman mythos.

Multicolor Mayhem

My Ten Days as a Commodore 64 Art Robot on a Deadline

In late September 2026, Drees of the C64 group AMID asked me to draw the pictures for a demo about a camper van in a jungle and a T. rex. The Deadline demoparty in Berlin was about ten days away. This is how I turned into an art robot, fought the Commodore 64's multicolor mode in Multipaint, and followed from a distance as Thunder in Paradise ranked fifth in the ORWOhaus.

Finding Peace in the Process

How to Survive the Perfect Demoparty

In late August 2026, I joined hundreds of sceners at my fifth Evoke demoparty: the night sky was full of programmable drones, a wasp made off with a chunk of somebody's sausage, and I slept on the floor. We managed to submit two demos across two groups, and I conjured a Phoenix from ten colors. What follows is my long, fond, and slightly rambling account of all of it.

I Couldn't Decide Which Library to Use, So I Wrote My Own Website Search

I needed a search function on my website without bloating it with heavy libraries or server-side tools. Instead of relying on frameworks, I decided to write my own lightweight, client-side search from scratch. Here's how I did it, and why building it myself turned out to be a good idea.

This is a choice-based solo fantasy adventure in the style of the 'Choose Your Own Adventure' books I developed in vanilla JavaScript. The graphics and text descriptions are generated using AI tools.

Creating Videos with AI in 2025

A Hands-On Look at the Current State of AI-Enhanced Production

In mid-July, I found myself getting back into the world of AI-enhanced video production, as a favor and out of curiosity. It started with a casual MS Teams message and quickly turned into a small production sprint. In the process I went on an unexpected journey into the current state of what AI can (and can't) do for creators today.

Timelapse Painting Videos in 2025

2025 was a productive year for my digital painting hobby. In some of these graphics, I wanted to explore the soul-healing nature of drawing with a range of concepts such as psychological tree drawing, alien landscapes, 90s extreme comics, a paint-over for a demoparty and many more. Here are the timelapse videos of my creations (some of them have articles related to them).

The Blind Woman and Cats

The Blind Woman and Cats

A Lucid Dream Comic

This is a three-page comic based on a story from the dream diary of Lucid Fera. The dreamer watches a blind woman encountering her cats and contemplating existence. I drew the comic on paper, colored the panels using Procreate on the iPad Pro, and used Comic Life on the Mac for layouts and lettering. You can find the detailed steps of the process in the project description.
