Cogimator – A Curated Directory of Unique Websites#
Cogimator.net is a carefully curated directory of websites that offer something more than just sleek design or trending buzz. It’s a collection of digital places created with passion — independent projects, experiments, and archives that challenge how we experience the web.
We don’t chase popularity. Instead, Cogimator focuses on originality, usefulness, creativity, and cognitive depth. You’ll find websites that are often overlooked by mainstream platforms — projects made by individuals, small teams, or devoted communities.
In short, it’s a curated directory of unique websites — assembled by hand, driven by curiosity.
We feature:
educational tools and visual simulations
cultural curiosities and digital micro-archives
experimental interfaces and interactive essays
artistic expressions and personal knowledge libraries
web-native projects that defy classification
Our mission is to:
support independent creators and timeless ideas
promote alternative knowledge sources
encourage slow exploration and digital curiosity
Most featured sites are:
non-commercial or ad-free
niche but high quality
thoughtfully crafted and often hand-coded
alive for years, yet virtually invisible to the average user
We believe in an internet that surprises, teaches, and inspires — a web that resists homogenization. If you’re tired of algorithms, top-10 lists, and over-optimized content, you’re in the right place.
🌐 Cogimator is where the unexpected web begins.
ExplainShell – Understand Shell Commands, Line by Line
🔗 explainshell.com is a brilliant utility for anyone working with Linux or Unix shell environments. While basic commands like cd or ls are commonly understood, more advanced command-line expressions can quickly become cryptic. That’s where ExplainShell shines – helping you understand exactly what each part of a command does.
The interface is refreshingly simple: paste in any shell command (e.g., tar -xzvf archive.tar.gz or find . -type f -exec grep -H 'pattern' {} \;) and the tool immediately dissects it. It maps each argument, flag, and operator to documentation snippets pulled from real man pages. You don’t just get a general explanation — you see which part of the command corresponds to which official description.

Randoma11y – High-Contrast Accessible Color Pairs
🔗 randoma11y.com is a surprisingly effective minimalist tool designed for web developers, interface designers, and accessibility advocates. Its main purpose is to generate random background/text color pairs that meet the WCAG 2.1 contrast ratio requirements, making them readable for people with visual impairments or low vision.
Upon each refresh, the site presents a new color combination, displaying both HEX values, the exact contrast ratio (e.g. 9.41:1), and a ready-made CSS snippet. Visitors can vote on whether the combination is good or bad, slowly building a kind of crowdsourced archive of aesthetically pleasing and functionally accessible color sets.

Sci-Hub – Access to Science Without Barriers
🔗 sci-hub.se is one of the most impactful and controversial websites in the history of online science. Created in 2011 by Kazakh programmer Alexandra Elbakyan, it offers free access to millions of academic research papers that are otherwise locked behind expensive journal paywalls.
Functionally, Sci-Hub is a minimalist tool: you paste in a DOI or article URL, and it returns the full PDF — instantly, without login, subscription, or ads. The site draws on both cached repositories and institutional access points to deliver content from publishers like Elsevier, Springer, Wiley, and others.

Ncase.me – interactive stories and educational simulations
Ncase.me is the personal website of independent creator Nicky Case, who crafts interactive simulations, explorable explanations, and narrative games designed to teach — and often challenge — how we think about the world.

Among the most notable projects are:
– 🔹 The Evolution of Trust – a powerful explainer on game theory and why trust breaks down;
– 🔹 We Become What We Behold – a short but searing exploration of media-driven polarization;
– 🔹 Coming Out Simulator – a raw and personal interactive narrative about identity and family;
– 🔹 Parable of the Polygons – a collaboration with Vi Hart on structural discrimination, expressed through geometry.
