Did you know you’re sharing your bed with thousands of tiny arachnids? 🧹 

Quinten Geldhof, also known as Microhobbyist, shows how a single spider can produce up to seven different types of silk, each with its own job. Sturdy dragline silk builds the web’s frame, while sticky blobs of silk set the trap for prey. Pound for pound, it’s up to five times stronger than steel, and a strand long enough to circle the Earth would weigh just 4.4 pounds! What would you use spider silk for?

I've always found it frustrating that we explain complex biological mechanisms using static diagrams.

So I built Anima.

It's an open-source Claude Code skill that generates detailed, interactive figures covering neurobiology, pharmacology, anatomy and molecular biology.

One of the examples lets you switch between cocaine and amphetamine to see how their mechanisms differ at a dopamine synapse.

Another visualizes D1 and D2 dopamine receptor signaling with interactive controls.

It currently has six working examples, scientific references, interactive animations and optional WebGL/3D support.

The entire project is MIT-licensed, and the demos run directly in the browser.
