//
// 世界：低い解像度で、約20色の番号だけで描く。時刻の変化はディザの置き換えで行い、中間色を作らない。
// 外側：真鍮とリベットの枠、窓の奥行き、液体のレンズを WebGL で描く。ピクセルは常に整数倍のまま写す。
// 灯り：世界の光る画素をぼかした「光の場」を作り、ガラスと外の面を照らす。人影が窓を横切れば、外の光も変わる。
// 時間：太陽の届かない海底で、基地の時計が昼と夜を作る。左端は昼の照明、右端は夜の消灯。
// 右へ動かすと 昼→夕方→夜。左へ戻すと 夜→深夜→点灯前→朝→昼 と、時間は前へ進む。
// 太陽のかわりに探査艇が頭上を渡り、月のかわりに大きなクラゲが昇る。星はマリンスノーになる。
