3D Fractals

This a response to a comment made on my ployhedra photos page. That question being : Is there an equivalent to a 3D fractal? The answer is yes. I have made only one on my computer. It's a Sierpinski Cube made of Legos. Of course, a great example that we see all the time is a tree. Trunk to branches to smaller branches to smaller branches to veins in leaves to smaller veins. Very cool!
