I built this fun visualizer to show how much physical commodity bitcoin buys. I ve launched with gold, silver, Plutonium-238, and one other substance that’ll never get a ticker symbol. And there s a dog for scale. It s all client-side math, open data, SvelteKit + Three.js. Click the Satoshi, Strategy, and US Govt presets to see what each stack buys, slide the slider all the way from 1 sat to 21 million bitcoin, turn on the Geiger counter when you find it.
