Party! Is a custom Particle System for Blender made using Geometry Nodes. It focus on ease of use, flexibility and speed, for beginners and expert Blender users.

Party! Features collision and self collision detection, with bounce and friction, easy trails generation and a variety of forces to modify the particle's behavior. You can access the particles attributes inside the shader using custom "Info" and "Hit Info" nodes.
