One teapot, seven hands. UNRSN tells one story seven ways — how a person shapes a surface from curves, from the light-pen constraint console of 1963 to the modern NURBS modeller, each room wearing the real software skin of its era. Pick an era on the rail above. The specimen is the field's oldest in-joke, the Utah teapot. The point is the hand.
Each room is a small school, and the count is the argument — seventeen lessons in the modern room, five at the 1963 dawn. Capability grows as you walk forward in time. The earliest room can't even make a surface — it draws a wireframe and constrains it; the surface arrives in 1977. Every later room builds the teapot for real, the period way — body, lid and knob revolved, spout and handle swept — with a ghost hand that walks each lesson start to finish. Every room also carries at least one specimen that ISN'T the teapot: the era's own day job — a truss bay, a Falcon-50 fuselage, a chair elevation, a turned tool handle, a car fender, a sheet-metal bracket, a solitaire ring. Sixty-eight lessons across the seven hands.
