This is a simple, lightweight P5 sketch captured to a low-res (320×240), compact video just to illustrate that it is easy to create animations with Processing.

Uploaded with Vimeo also, but Vimeo makes non-paying users wait.

Here is the same P5 sketch rendered at 720p (watch full screen):

The lower-resolution video was made using the built-in MovieMaker class. The 720p version was made by saving each frame as a png image file by calling the saveFrame() method. The frames were then concatenated and saved in mp4 format using FFmpeg.
