Before we move on, it's worth mentioning the relationship between this variation and the Sierpinski Gasket.
Specifically, we can think of the Gasket as a fractal flame that uses only the linear variation.
### Julia (variation 13)
This variation still uses just the $x$ and $y$ coordinates, but does crazy things with them:

The formula looks intimidating, but it's not hard to implement:

TODO: Mention that the Sierpinski Gasket is just a blend with linear weight 1, all others 0. Maybe replace comment above about Sierpinski Gasket and linear transform?
TODO: Blending implementation?
And with that in place, we have enough to render a first full fractal flame:
