Mysterious Grasshopper Components

Hi Everyone,

I’m a newcomer to this forum and to Grasshopper. I’ve been trying to figure out how to create an inflated voronoi pattern (like the Beijing Olympic water cube) and apply it to a surface. Anyhow, I’m stuck because I can’t figure out what some of the components are on a diagram from a post on the Grasshopper forum. I’ve posted there to ask already the guy who posted it already. If you guys can help me identify the below components, that’ll be great:

Mystery Component 1
Mystery Component 2

BTW, here’s the link to the post:

Thanks,
Ivan

Thanks Laurent! I have them now. But now figuring out what’s wrong with my model.
