竹知了3D - 听取哇声一片，儿时的乐趣
摇的越快叫的越急，明月别枝惊鹊，清风半夜鸣蝉。
Free · Designed for iPad. Not verified for macOS.
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。
