先展示几个吧

数学公式：


c_{r}=\operatorname{rgb}(191,10,48)

c_{b}=\operatorname{rgb}(10,49,97)

c_{w}=\operatorname{rgb}(255,255,255)

0<=x<=19\left\{0<=y<=10\right\}

\operatorname{polygon}((0,0),(19,0),(19,10),(0,10))

0<=x<=19\left\{\operatorname{mod}(\operatorname{floor}(y\cdot1.3),2)=0\right\}\left\{0<=y<=10\right\}

0<=x<=7.6\left\{\frac{60}{13}<=y<=10\right\}

I_{s}=[0...10]

X_{s}=0.306\cdot\left(1-0.62\operatorname{mod}(I_{s},2)\right)\cdot\cos\left(I_{s}\cdot\frac{\pi}{5}+\frac{\pi}{10}\right)

Y_{s}=0.306\cdot\left(1-0.62\operatorname{mod}(I_{s},2)\right)\cdot\sin\left(I_{s}\cdot\frac{\pi}{5}+\frac{\pi}{10}\right)

k_{1}=[0...359]

n_{1}=\operatorname{floor}(\frac{k_{1}}{12})

C_{x1}=\left(2\operatorname{mod}(n_{1},6)+1\right)\cdot\frac{7.6}{12}

C_{y1}=\left(2\operatorname{floor}(\frac{n_{1}}{6})+1\right)\cdot\frac{7}{13}+\frac{60}{13}

晒一下简简单单的年夜饭，以及我老弟玩的烟花

但是楼下太冷了,不想亲自去放，所以俯瞰视角

不知道佬友们那边能不能放烟花，上传不了视频，只能上传一下图片了，佬友们凑合看
