Eye Simulation explores human and animal vision in 3D

Claude wrote an interactive browser model while the maker chose species, researched anatomy and tested the behaviour. Missing published values are labelled estimates.

The full story

Eye Simulation lets visitors choose a human or animal eye, change its anatomy and explore how the model represents its view of the world. A 3D cutaway labels eye structures and explains their roles.

Claude wrote the HTML, CSS and JavaScript, including Three.js for the eyes. The maker directed design and research, selected animals and settings, checked values against published studies and tested the behaviour. When no published value was available, the app labels it as an estimate. It is an interactive educational model rather than a clinically validated vision test.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
