Did you possibly mean caput?
- n. a land imagined by Jonathan Swift where impractical projects were pursued and practical projects neglected
“Elizabell, an engineering genius, teams up with her new benefactor to build a laputa, an island in the sky.”
“as for specific stuff: i'm thinking laputa: castle in the sky and nausica in the valley of the wind will be 'adult' enough, though kiki's delivery service and totoro are 100% win.”
Looking for tweets for laputa.
