An interactive map of 500 technologies spanning 3.3 million years of human invention, from stone tools to artificial general intelligence.
The tree uses polar coordinates with a parabolic funnel boundary (θ ∝ r²). Distance from the center is time — prehistoric origins sit near the hub, modern and AI-era technologies ring the outer edge. The funnel is narrow at the trunk (few root technologies) and widens quadratically into a broad canopy. Within the funnel, a 45° fan is divided into 12 domain sectors (Materials, Energy, Computing, Medicine, etc.); hex packing fills the available space at each radius.
Each circle is a Wikipedia article. Nodes maintain a constant pixel size at any zoom level and hex-pack to avoid overlap when zoomed out. Wikipedia thumbnails load automatically. Border color indicates the technology's domain; legendary-rarity nodes glow.
Lines connecting nodes are prerequisite relationships — you need the parent technology before the child becomes possible. Edges connect the displayed hex windows directly, so they track the actual visual positions at any zoom level.
Each technology has an era, domain, year, status (alive/dead/evolved), complexity (1–10), rarity, and a list of prerequisite technologies. The pool is curated for a “rebuild civilization” scenario — what would you need to reinvent if starting from scratch on another planet?
