A user asked Claude to build a nuclear plant simulation. After churning for 90 minutes and burning 700K tokens, it produced an incredibly detailed interactive model where every component can be clicked to reveal its parameters — all physically modelled, albeit with simplified physics. A striking demo of long-horizon coding capability.
