Infinite canvas notes in the non-Euclidean Poincaré disk
Hi! This is an infinite canvas note-taking tool where notes are laid out in a non-Euclidean, hyperbolic geometric space. As you drag and navigate through the view, you’ll experience a unique fluid distortion that naturally leverages your brain's spatial memory. I’ve been obsessed with the concept of space in HCI for years. Many modern UI patterns are essentially workarounds for the lack of screen real estate. While researching zoom-based UIs a while back, I stumbled upon old HCI papers that used the Poincaré disk model of the hyperbolic plane to organize data. It elegantly projects an…

In plain words
This is an infinite canvas note-taking application that organizes notes using hyperbolic geometry within a Poincaré disk model. As users navigate and drag through the interface, the non-Euclidean space creates fluid visual distortion designed to enhance spatial memory retention. The tool projects infinite space into a finite disk, keeping all content contextually visible while addressing screen real estate limitations common in traditional note-taking interfaces.

NodeLand2024 · nodeland.io · ▲533Hello, HN! Have you ever considered that you might be a visual thinker? A lot of studies emphasize the benefits of visual thinking in learning, as it activates different parts of the brain and enhances comprehension and retention. It is common, for example, to remind yourself of a concept by visualizing the page where you wrote it down. This is because the brain is more likely to remember visual information than text. Unlike traditional linear note-taking apps like Notion and Evernote, NodeLand introduces a revolutionary connection-based model. Everything you write is seamlessly integrated…
A canvas-based note taking and organizer appJul 2026 · passinote.app · ▲61So I've been working on this app for a very long time now. Started off by wanting an app that separates long form notes from short form notes visually and keeps everything organized on a canvas. The app features: -Sticky notes for quick, small notes and A4 notes for long form documents -A quick mode that uses local storage to quickly open the app and jot down a thought on the canvas -A PDF export option that exports your notes into 3 custom designed PDF styles -Visual hierarchy to replicate file structure instead of a linear fashion, where your files are notes, stacks are folders and labels…
Visualize rotating objects from the 4th, 5th, nth dimensions2023 · ncube.ndavd.com · ▲181Ever since I remember I had a lot of curiosity regarding hyper dimensional spaces. Picturing higher dimensions, such an impossible yet exciting idea... So years ago I came across a small GIF of a tesseract. Since then it left me wondering how cubes from even higher dimensions would look like... Years passed and I became a software developer, decided to tackle the problem myself and ncube was the result. ncube allows you to visualize rotating hypercubes of arbitrary dimensions. It works by rotating the hyperdimensional vertices and applying a chain of perspective projections to them until the…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
