Introducing tiny.london A massive isometric pixel map of London, based on amazing NYC demo by @_coenen from 9 months ago My agent created the dataset, finetuned qwen image LoRA adapter, did a multiday inference run and built an efficient tile viewer!
I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code.

If I were forced to pick one scene in Lynch's run that encapsulates his art (which is impossible), my pick is the Llorando sequence in Mulholland Drive. Even in the dark of our nightmares, the beauty and pain of art can reach us, even if that art is built on nightmares itself.

He was the worst President in history. And when he got voted out, he tried to stage a coup. Then he stole national secrets and sold the ones he didn't store in the bathroom. He was convicted of fraud, found liable of sexual assault and convicted of 34 felonies. He is half a billion dollars in debt, owned by God only knows who, and the biggest national security risk the nation has ever had. But at least he's not a Black woman.

Thanks Jeff Lawson for buying the Onion so we could get this great zoom in on electoral coverage. No other news source has gone to this level of detail.

We just dropped in on Liz Truss’s pro-Trump speaking tour with a remote-controlled lettuce banner. She didn’t find it funny. 🥬

High-Rise is such a prophetic novel that it’s almost unbelievable at times. Ballard doesn’t just predict social media here, he doesn’t just predict Instagram, he predicts Instagram Stories, and he does so with such insane precision that he specifically mentions the FILTERS. 1972!
