# Iridiation of (algebraic|transcendental) varieties and strange attractors.

Suppose I have an algebraic variety $G$ in $\mathbb{R}^{n}$ — or a strange attractor $X$ in $\mathbb{R}^{3}$, and to each point of $G$ or $X$ I associate a unit sphere — in the case of $latex{R}^{3}$ I could use Riemann spheres at each point $u$ of $X$ or $G$, and then say: okay, when I make visualizations of $G$ or $X$, the color I see from the vantage point I’m looking at the variety or strange attractor is the phase/hue whatnot I get when I take some function $f:\mathbb{C}\rightarrow\mathbb{C}$: every point has a sphere associated with it, colored by phase of $f_{u}$

Terminology: if it’s a variety, we call them iridiated varieties or iridovarieties.

The inverse (or adjoint functor if you will) should be called bleaching.

And http://en.wikipedia.org/wiki/Iridescence is the right word here: these are objects whose appearance changes as you change the angle that you’re looking at them.
