## Hilbert Curves

This is a cool sculpture inspired by a **Hilbert curve**, made from what looks to be left-over metal piping.

A Hilbert Curve is constructed through an iterative process that is repeatedly **self-similar**. You start with a simple, bent path around the inside of a square, and then you take each straight part of that path and bend it to make it look what you started with. And repeat. Ad infinitum.

Given the infinite self-similarity (and some other properties), the Hilbert curve is a kind of **fractal. ** A nice visual illustration can be found at Wikipedia: http://en.wikipedia.org/wiki/Hilbert_curve.

What’s especially interesting about **Hilbert curves **is that they essentially “fill up” the plane. This is seemingly paradoxical, in that you have a one-dimensional object (a path) that ends up equivalent to a two-dimensional object (a plane). For this reason, these are also referred to as **space-filling curves**.

I already have one plant that might be a fractal; I’ll be on the look-out for a space-filling vine!
