一根竹签,一条细绳,绳头拴着一只竹筒做的知了。 手指划着圈把它甩起来,它就绕着签头转,转一圈,叫一声。 摇得越快,叫得越急。 这是很多人童年记忆里的那只竹知了。 如今我们把它一比一搬进了手机:竹纹、红漆、烙画的翅脉、 两颗黑木珠眼睛,都照着老玩具的样子重新做了一遍。 ■ 真实的物理,不是动画 知了是被真正「甩」起来的。转速越高,离心力把绳子甩得越平, 它扫出的圈子越大——这是圆锥摆,和你小时候手里那只一模一样。 ■ 声音是算出来的,不是录音 竹膜上那根松香线的「黏—滑」摩擦,被一比一建模成了声音: 摩擦脉冲、竹腔共鸣、随公转扫动的共振峰, 凑成那声拖长的蝉鸣。转得越急,叫得越密。 每一次响都是实时算出来的,所以每一次都不重样。 ■ 手指划圈,也可以摇手机 划圈甩,或者直接晃动手机,两种玩法都行。 ■ 想让它喊什么,它就喊什么 「哇」可以改成任意四个字。你写什么,它就一路喊着什么转。 ■ 四种背景,一个清屏模式 纯黑、柳影、叶隙、光斑随你挑。 点左上角进入清屏,满屏只剩一只知了在转。 明月别枝惊鹊,清风半夜鸣蝉。 夏夜的声音,收在手机里了。
