For PCD Japan 2021, we organize Daily Coding Week from Feb 13th! We made a "prompt list" as themes of the day, and those works tweeted with #PCD2021 by 23:59 (UTC+9) will be automatically included in our 3D online gallery! Use your favorite tool (not only p5/p5js) for submission! pic.twitter.com/WjcOwu1fnP
