# ComfyUI Illusion & Pattern Nodes This repository contains a collection of custom nodes for ComfyUI, designed for generating various patterns, optical illusions, and performing related image manipulations. All nodes are categorized under "illusion" in the ComfyUI menu. ## Installation 1. Navigate to your ComfyUI `custom_nodes` directory: ```bash cd ComfyUI/custom_nodes/ ``` 2. Clone this repository: ```bash git clone https://github.com/orion4d/illusion_node.git ``` 3. Restart ComfyUI. The nodes should now be available in the "illusion" category when you right-click or use the "Add Node" menu. ## Nodes Overview Below is a summary of each node provided in this pack: --- ### 1.
