Show HN: A guided 3D Leonardo da Vinci museum, built in code Hello HN, I am the founder of a small nonprofit which built Museum of Ages. We opened its first wing last week, a digital Leonardo da Vinci museum. It is a virtual tour with 17 stops, his works and then his last house in Amboise. The entrance is free. At the different stops you can see for example his paintings close to their real size, or 15 of his machines rebuilt in code, and you can have a look at 29 of his anatomy sheets. We also selected 207 of his manuscript pages which you can read in a virtual reading table, mirror the view to read his writing and 131 of the 207 are translated. We also rebuilt his last house in Amboise on the later stops of the walk. The museum is available in seven languages. Each stop has one of four grades as a label, documented, reconstructed, conjectural and not known. In a detailed view the user can have a closer look at the sources. The materials of the rooms and machines are created in Three.js. The museum runs with WebGPU. If the browser doesn’t support it, the fallback is WebGL2. To create the textures we used Creative Commons Zero photo scans (CC0) and for a few small objects we use free 3D models (CC0). Our mission is to create digital museums you can walk as not everyone can get to a museum, because illness or disability keeps them away. Some cannot afford the trip or just reside far away. So our goal is also to make our digital museums as accessible as possible. Therefore we also pre-rendered the walk so that it also works on older phones and is easy to use for older people. We released the code under AGPL-3.0. The texts and pictures are CC BY-SA 4.0. Reproductions have their own licenses. https://ift.tt/UGqbN85 We put a lot of time and passion into the museum and hope you like it. We are happy about any feedback. Which digital museum would you like to see next? https://ift.tt/5asGheq October 14, 2026 at 12:00AM

Show HN: shadowclone, skills learned from your coding agent corrections https://ift.tt/adPijFG

Show HN: shadowclone, skills learned from your coding agent corrections shadowclone reads the coding-agent sessions already on your disk, finds where you corrected the agent and turns those corrections into skills your agents load next time. It supports Claude Code, Codex, Cursor, Pi, and Antigravity. Every capture source is off by default and has its own consent setting. Why I'm building it? I use multiple harnesses and agents, I extensively use Claud Code and Codex, but I also use Cursor and Antigravity every now and then. I didn't want to have to teach every harness or model the things I taught the other ones between my last session and the current one. I also cannot have my personal rules and preferences in all the repositories I work on because my collaborators may have varying levels of trust with AI and their own preferences. shadowclone helps me build and improve trust with my agents so I can give them more autonomy while running multiple sessions in parallel. --- Who is this for? If you only use Claude or Codex or any one of these, you may not need the shadowclone CLI and the harness and agent you use might already be sufficient. But, if you are like me and work across harnesses and agents, shadowclone will help you avoid repeating your preferences each time. --- Built-in skills and skill builds shadowclone is also great for someone who is just now adopting AI into their coding workflows because it ships with several skills that they can use to customize their agent's behavior. They can equip all the skills, or just some of them, they'll see the "personality" their agent gets from equipping those skills from the `shadowclone wizard`. --- Setup is extremely easy, just ask your Claude Code, or Codex, or another agent - "Set up shadowclone: https://ift.tt/cZoOavY... " --- Privacy shadowclone is free and open source, it uses the MIT license. It doesn't have a subscription, or a server. It just uses your existing agent subscription i.e. Claude Code, Codex, Cursor, Antigravity, or even your local model via Pi. You can explicitly disable sources, it also redacts any and all sensitive information it uses for learning. --- PR reviews and Cloud bots It can review PRs with the `shadowclone review` command, it ships a guided review skill that will perform a deep review of your code (or someone else's) and produce an HTML document you can annotate, add comments to and submit so your agent can stage a draft review on the PR you are reviewing. --- Evals I performed several evals, I won't describe them here, all of them are available in the repository - https://ift.tt/MyzIuZ6 --- Comparison to other tools? You can also see how it compares to other tools here - https://ift.tt/uMRsXNP... https://ift.tt/bZQrGJn October 13, 2026 at 12:26AM

Show HN: Teilifís Seán – A Jellyfin Plugin for Channel Surfing https://ift.tt/KRCLENA

Show HN: Teilifís Seán – A Jellyfin Plugin for Channel Surfing No Setup, Works immediately once installed with sensible defaults. Extremely lightweight. A demo on the site with no installation required to see how it works. I'm a Developer in Ireland. This is for Jellyfin admins who don't want the overhead of another app in their docker/server setup but also want that nostalgia feeling of channel surfing your own content to find something. I built this as a fun and simple alternative to the likes of Tunarr or ErsatzTV which require quite a bit of setup and support a lot of configurations they also require transcoding and place a large burden on your server, this adds zero burden but they have the added benefit of working on the Jellyfin TV app. This works only in a browser. Jellyfin 12.x only. GPL, OpenSource. Why? Content discovery, have you ever just sat staring at your Jellyfin library paralysed by choice? This is for you. Would love feedback especially from people who have had to configure Tunarr or ErsatzTV. https://ift.tt/Nsl6p4D October 12, 2026 at 11:50PM

Show HN: Nitro – a Python static site generator Build static sites in Python instead of a template language. Pages are functions, HTML is Python classes, and the build is a folder you can host anywhere. No complexity, just code. Its not 'new', but someone could find it useful. https://nitro.sh October 12, 2026 at 03:15AM
