This time we'll create the "plexus" effect with Geometry Nodes inside of Blender. Manuel shows you how to abuse geometry to fake a loop, that tests all connections between the points of an incoming point cloud and compares their lengths. Then, only the ones are drawn, that are shorter than a certain threshold, creating an intricate geometric pattern.
