A simple fractal (Sierpinski's box) made with a small macro. Made out of
160000 superellipsoids.

Why superellipsoids, and didn't that make it render like a dog?

But very pretty.

Bye for now,

Looking at the way you sort of moved some of the cubes at the bottom away
from their natural positions made me realize that you could create some
really cool animations with this. Imagine keeping an array of four or five
points moving around more or less randomly within the fractal, and all the
cubes being repelled by them by an amount inversely proportional to their
distance from them squared. It'd make it all bumpy and stuff. Slow to
render, but it may look cool.

Nice image, anyway. I like fractals.

Isn't it called the Sierpinski sponge?

Menger sponge.

An extrapolation of the Sierpinski Gasket; each specific fractal has
three or four different names anyways...

I thought the Sierpinski gasket was triangle-shaped..
Oh well... never mind.
