cool
really cool!
good
This is so cool, I'm just amazed by this thank you for sharing!
One of the simpler ways to make an octagram like yours is to recognize it as two overlapping boxes. One of them is rotated by 45 degrees, and the union operator can be used. However, this method is bound in the interior.

Mesmerizing kaleidoscopic symmetry and detail—it feels like looking into a crystalline universe.
love this!
Beautiful !!!
Very cool!
