Abstract Hollows

I used cylinders twisting two separate ways for this one.

This one is made from "L" shapes rotated, tapered, and twisted.

This was made by bending & duplicating. 

                              Created by placing many cylinders, followed by twisting tf out of them.                                 

All made of cones stacked on top of each other.

I used walls & a LOT of commands.
