In the video below, Simon is showing the cloud design he contributed to the community project collecting cloud designs for the Processing Community Day coming up on October 21, 2017. You can play with Simon’s design on the community project webpage created by Coding Train at https://codingtrain.github.io/CommunityClouds/
Simon’s cloud is called “Round Cloud”. Once you open it on the Coding Train Community Clouds page, the cloud changes its shape every time you click on it.
