dailycodingchallenge 4/6 漢字. openFrameworks

[ Video ]

[ About ]
Twitterで行われている #dailycodingchallenge にチャレンジしました。4月6日のお題は「漢字」です。
オブジェクトはお互いに反発しながら、近づくと線を引きます。中央には線の数を”漢字”で書かれます。

I took part in the #dailycodingchallenge on Twitter, and the theme for April 6th was “Kanji”.
The objects repel each other, drawing lines as they approach. In the center, the number of lines is written in “Kanji”.
