Welcome to Marin's Digital Playground

Creativity meets technology. Join me as I dive into a world where programming exercises reveal not just code, but the stories behind them. Follow the things I learn in public and the mistakes I make. Let's explore vibrant hackathons, the incredible demoscene, archaic yet inspiring retro computers, and quirky comics.

Drawing as Meditation

The Ritual of Lines That Calm the Mind

I like drawing. I'm not particularly good at it, but it makes me happy. It slows me down, sharpens my attention, and teaches me to accept imperfection. This is not an article about getting better at drawing, it's about what happens while you draw. Join me as I work through four different graphics and share what I learned about the quiet power of making something slowly, with my hands.

From Zero to Koala

Learning to Draw for the Commodore 64 to Compete at Transmission64

I joined the demogroup VCC to make graphics for their Commodore 64 demo without ever having drawn a pixel for this machine. Now my chunky images are part of a quirky Ski Jumper demo, released at the remote demoparty Transmission64 in late November. I learned more about retro art, collaboration, and community than I expected. This is my "making-of" and demoparty report.

Speedrun of the Retro Gaming Museum in Vienna

I hope you love retro computers, joysticks with microswitches and the glow of arcade screens just as much as I do. I spent a delightful evening underground in a WWII bunker filled with beeping, blinking nostalgia. This quick tour of the Retro Gaming Museum in Vienna is light on text but heavy on photos.

The Game of Test-Driven Development

A Day of Coding and Experimentation Above the Rooftops of Vienna

On a crisp November Saturday, about thirty developers gathered at SQUER's Vienna office to practice Test-Driven Development. We learned, experimented, and rediscovered the joy of crafting code. One key takeaway stood out for me: it's okay to learn from things you make and then throw them away.

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.

Mansion of Trepidation

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. The player can search the 'Mansion of Trepidation' to defeat the villain and rescue their young nephew.

A Wide Variety of Videos

Over the years, I recorded a number of Youtube videos on many different subjects like the Bitmap Brothers game "Chaos Engine" on the Atari ST, about the iPad apps that support the full resolution on external displays, on how to draw Captain America and a number of different design topics.

Creating Videos Using AI

Using AI Tools to Make Explainer Videos

What if you could create your own explainer videos without much effort? I decided to try it myself and made three explainer videos in only one day using generally available and cheap artificial intelligence tools. The results are perfectly workable. Take a look at the three videos that came out.

Comics
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.

Timelapse Painting Youtube Videos

Timelapse Painting Youtube Videos

These timelapse videos show the process I use to paint pictures on the iPad Pro with an Apple Pencil 2 in ProCreate. They are quick and easy to make because ProCreate is superbly snappy and delightful for quick paintings and I can record the process automatically using the built-in feature in the application.
