This script can render avi's and gifs. Setup recording in setup(). 

  Press enter to start and stop recording.

  Will also stop recording after full cycle. Use this for perfect loops :)

​

  Feel free to share your gifs on my discord server! 

  https://discord.com/invite/DxbUee2y6D

  (max upload 8mb)   

  recommended gif settings:

    canvas size: 500x500

    quality: 1 (highest for 'accurate' colours)

    fps: 30 (or lower to save space)

    frames: 500

  libraries used:

    Video Builder: https://github.com/theshock/VideoBuilder

    gif.js: https://github.com/jnordberg/gif.js
