Draws window frost patterns as trees connected at origin.
Some are pairs of trees, some have up to six trees, like snowflakes. See the branching characteristic of conifers. The pattern is roughly fractal. This type of branching is different than the typical fractal trees, in which each single branch ends at the point that it splits into two (like a deciduous tree). By contrast, trees used here has branches that continue such that each single branch continues even as it adds two branches. Notice this type of branching is characteristic of conifers, also called evergreens.
