[ About ]
Paticleの距離が近づくと線が引かれます。
距離によって色の濃さが変わるようにしてあります。

When the distance of Paticles approaches, the line is drawn.
It is made to change color intensity depending on the distance

[ About ]
円のz座標をnoise関数(x, y, フレーム数 – 円数)で計算しています。

The z coordinate of the circle is calculated by the noise function (x, y, the number of frames – the number of circles).
