The Legend of Zelda: Wind Waker originally had Link play theremin, rather than conduct the winds using his titular conductor’s baton.
Miyamoto also had things to say around Wind Waker’s cel-shaded art style – but Aounuma had apparently anticipated this to a degree.
To counteract this, Aounuma waited to show Miyamoto the new art style – though Miyamoto apparently “had trouble letting go of the realistic Link art style until the very end”.
Eventually, Link’s hand movements were changed to a baton – and the Wind Waker itself was born.
