Annoyed by messy After Effects comps? With Workflower, you can create layer groups within your comp, as well as use other workflow-enhancing tools, like adjustment layers to selected layers only, layer cloning, or matte merging.

https://aescripts.com/pixel-stretch/

Pixels are stretched on a subpixel precision according to their brightness. The stretching is cumulative for every row or column, which means a pixel offsets all the following pixels on its line. This produces much more organic looking patterns compared to what you get using simple effects like "line stretch". The basic effect is similar to what you'd get on an old analog TV, but all the knobs this filter provides give you much more possibilities!

 Rowbyte Plexus 3.2.6 for After Effects

 Plexus is a plug-in designed to bring generative art closer to a non-linear program like After Effects. It lets you create, manipulate and visualize data in a procedural manner. Not only you can render the particles, but also create all sorts of interesting relationships between them based on various parameters using lines and triangles. The workflow for Plexus is very modular allowing you to create truly infinite set of configurations and parameters.

RetroDither is a GPU accelerated plugin for Adobe After Effects which allows to create stylized images with dithering and color schemes from retro game consoles and home computer platforms.

You could call it ‘save GIF for web’ on steroids on first sight, but in fact RetroDithering is capable to do so much more, having more than 10 different ordered and errordiffusion dithering algorithms and color palettes varying from several adaptive to classic hardware ones, such as ZX spectrum, CGA, MSX and many more.
