• A point generate geometry node creates a single source point
• An attribute wrangle creates three new attributes for the point used for the mitosis animation:
• float @age
• float @numChildren
• vector @velocity
• A jitter node which is useful if the generate node is used to create more than one point
• A solver node to iterate over the geometry and is where the magic happens
