Need to tone down some of these colours, but I love how the fog flows now.
Got slightly obsessed and turned the Golden Ratio Colour Scheme Generator into a thing. codepen.io/jonikorpi/fu...

Golden ratio hue rotation

Oh, only just realised you can generate colour schemes with golden ratio rotation to automatically get good hue contrast.
```js
const mainHue = 0.0 * Math.PI * 2.0;
const steps = 8;
const hues = [];
for (let step = 0; step < steps; step++) {
hues.push(mainHue + Math.PI * 2.0 * 1.618);
}
```
```js
const mainHue = 0.0 * Math.PI * 2.0;
const steps = 8;
const hues = [];
for (let step = 0; step < steps; step++) {
hues.push(mainHue + Math.PI * 2.0 * 1.618);
}
```

New Paper: Game Design is Generative Design. Designing a procedural generator and designing a game share a lot of skills, problems and philosophies, even if we think of them as distinct. I try to connect them here, for good!

I like how full text search of every book and human thought ever was a SOLVED PROBLEM in 2001, and now dicks at search engines and my own phone – a piece of silicon faster to respond than God was ever imagined in scripture – prevent it from working, _as a retroactive infantilizing design choice_.

"Computers [and phones] became an A/B tested telemetry-based advertising conduit to brains for SaaS recurring revenue."
Computers were a skill. They were taught in classrooms as a skill. Skills give you power over your tools because you work them as an expert and that is leverage to multiply externally.
And then computers became an A/B tested telemetry-based advertising conduit to brains for SaaS recurring revenue.

It pains me that there is an entire generation of people who have now grown up trained to view manipulative, engagement-farming gambling games as the norm for video games.
There are countless people who have formative, nostalgic memories of opening loot boxes and the excitement of gacha ten-pulls

I've implemented "memory capture" for my procedural game about exploring and connecting clues. It's like taking photos of eligible objects, with automatic framing. It reduces the need for (manual) memorization.
For now, it's just the last memory; later a menu with all the photos. #GameDev #IndieDev

Bummed we're missing the auroras this time: 100% cloud cover last night and tonight too. Happy to see others are posting some good cosmic horror ray shots though.

Still gonna update the Map Preview, to use the same assets as the original maps, so it's more easy to know what is happening

sidenote that if I had played Öoo (store.steampowered.com/app/2721890/...) before I wrote my IGF thread it absolutely would have been on it. genuinely one of the best platformers I've played. 3 hours of all killer no filler and does more with two buttons than most games do with a full controller

Pixar designed Toy Story to be printed on physical film. The Disney renaissance movies were the same.
Today, it's hard to see them as they were meant to be seen. The versions on streaming and home media aren't quite the same films that ruled the '90s:

📖 Explainers for the templating API and DOM scheduler API
🏗️ Full prototype implementations
