Aether is a creative web platform to conceive, iterate, and visualize impossible architecture—gravity-defying volumes, non‑Euclidean geometries, and parametric structures with realistic behavior. It combines an in‑browser physics engine with a generative assistant to push “unbuildable” ideas to their limits while keeping control of materials, loads, and assemblies. Lightweight, fluid, and private by default, with multi‑device sync and a modern Liquid Glass UI.
