Ultra Fire Flower

One of the techniques I didn't understand until recently is the opacity value for an iterator. With opacity = 0, an iterator can influence the shape of the render without making any distinct mark. This is actually a pretty basic thing, but I skipped over it in the cluttered UI until recently. In this render, only 2 of the 5 iterators are actually drawing, but the other 3 play a big role in creating the detail.
