Hey HN!

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.

Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped!

I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity:

http://cannoneyed.com/projects/isometric-nyc

I was extremely excited until I looked closer and realized how many of these look like ... well AI. The article is such a good read and would recommend people check it out.

Feels like something is missing... maybe just a pixelation effect over the actual result? Seems like a lot of the images also lack continuity (something they go over in the article)

Overall, such a cool usage of AI that blends Art and AI well.

Edit: i see now, the error is due to the cloudflare worker being rate limited :/ i read the writeup though, pretty cool, especially the insight about tool -> lib -> application

This isn't creative. It's just a slog. Every creative field - animation, video, software - is full of these tedious tasks. Of course, there’s a case to be made that the very act of doing this manual work is what refines your instincts - but I think it’s more of a “Just So” story than anything else. In the end, the quality of art is defined by the quality of your decisions - how much work you put into something is just a proxy for how much you care and how much you have to say.

Great insights here, thanks for sharing. That opening question really clicked for me.

So, wait: this is just based on taking the 40 best/most consistent Nano Banana outputs for a prompt to do pixel-art versions of isometric map tiles? That's all it takes to finetune Qwen to reliably generate tiles in exactly the same style?

Also, does someone have an intuition for how the "masking" process worked here to generate seamless tiles? I sort of grok it but not totally.

I love it! Such a SimCity 2000 vibe!

Probably the best pre-AI take of the isometric pixel art NYC is poster from the art collective eboy. In the early 2000s their art was featured in MoMA (but I don't remember the NYC poster specifically).

> This project is far from perfect, but without generative models, it couldn’t exist. There’s simply no way to do this much work on your own,

Maybe, though a guy did physically carve/sculpt the majority of NYC: https://mymodernmet.com/miniature-model-new-york-minninycity...

Author here: Just got out of some meetings at work and see that HN is kicking my cloudflare free plan's butt. Let me get Claude to fix it, hold tight!

This is so cool! Please give me a way to share lat/long links with folks so I can show them places that are special to me :)

I was most surprised by the fact that it only took 40 examples for a Qwen finetune to match the style and quality of (interactively tuned) Nano Banana. Certainly the end result does not look like the stock output of open-source image generation models.

I wonder if for almost any bulk inference / generation task, it will generally be dramatically cheaper to (use fancy expensive model to generate examples, perhaps interactively with refinements) -> (fine tune smaller open-source model) -> (run bulk task).

You mentioned needing 40k tiles and renting a H100 for 3$/hour at 200tiles/hour, so am I right to assume that you spend 200*3=600$ for running the inference? That also means letting it run 25 nights a 8 hours or so?

Cool project!

To take it a step further it would be super cool to so rhiw figure out the roadway system from the map data and use the buildings as masks over the roads and have little simulated cars driving

Nice work! But not all of NYC. Where's the rest of Staten Island?

amazing work!

gemini 3.5 pro reverse engineered it - if you use the code at the following gist, you can jump to any specific lat lng :-)

One thing I learned from this is that my prompts are much less detailed than what author has been using.

Very cool work and great write up.

A bit tangential but i really think the .nyc domain is underappreciated.

SF/Mountain View etc don't even have one! you get a little piece of the NYC brand just for you!

Failed to load tiles: NetworkError when attempting to fetch resource.

Nice, very cool!

Reminds me of https://queensmuseum.org/exhibition/panorama-of-the-city-of-...

This is very cool, it would be awesome if I could rotate it as well by 90 degree increments to peek at different angles! I loved RCT growing up so this is hitting the nostalgia!

Amazing. Took forever but I found my building in Brooklyn as well as the nearby dealership, gas station, and public school.

Insane outcome. Really thoughtful post with insights across the board. Thanks for sharing

Love that. I've been struggling to succinctly put that feeling into words, bravo.

Seems to have been hugged to death as of now

Some people reported 429 - otherwise known as HN hug of death.

You probably need to adjust how caching is handled with this.

This is kind of beautiful. Great work! I mean it.

This is huge!

At first I thought this was someone working thousands of hours putting this together, and I thought: I wonder if this could be done with AI…

This doesn't really look like pixel art; it looks like you applied a (very sophisticated) Photoshop filter to Google Earth. Everything is a little blurry, and the characteristic sharp edges of handmade pixel art (e.g. [0]) are completely absent.

To me, the appeal of pixel art is that each pixel looks deliberately placed, with clever artistic tricks to circumvent the limitations of the medium. For instance, look at the piano keys here [1]. They deliberately lack the actual groupings of real piano keys (since that wouldn't be feasible to render at this scale), but are asymmetrically spaced in their own way to convey the appearance of a keyboard.

None of these clever tricks are apparent in the AI-generated NYC.

On another note, a big appeal of pixel art for me is the sheer amount of manual labor that went into it. Even if AI were capable of rendering pixel art indistinguishable from [0] or [1], I'm not sure I'd be impressed. It would be like watching a humanoid robot compete in the Olympics. Sure, a Boston Dynamics bot from a couple years in the future could probably outrun Usain Bolt and outgymnast Simone Biles, but we watch Usain and Simone compete because their effort represents profound human achievements. Likewise, we are extremely impressed by watching human weightlifters throw 200kg over their heads but don't give a second thought to forklifts lifting 2000kg or 20000kg.

OP touches on this in his blog post [2]:

Really nice.

Hugged to death? :(

beautiful!
