Cylindrical shape

Hello im kinda new to rhino and grasshopper, but i want to try to make a similar shape to this picture, idk if someone knows waht kind of tool to use to be close to a shape like this. Is teh work of Rameshwari Jonnalagedda and is so cool i really want to practice doing something similar like this. thanks

There are many excellent tutorials available on this forum and YouTube for creating similar shapes. You can definitely achieve this using Rhino. This is a thread I have just read: Gyroid Between 2 Nurbs Surface - #2 by martinsiegrist

also have a look at Isopod
