Humans and Nature (人間と自然) is a depiction of nature in the language of mathematical curves, and people as spheres living their lives among lines. The settings are an abstraction of life in the universe, on the planet, in nature, in the neighborhoods and cities. We start at the beginning of time, there is an expansion of the space, and we find our places in the universe with each other, or alone at the corners.

Max resolution of preview image is 1500x1500 px (プレビューの最大解像度は１５００x１５００pxです）
s - save preview image/current image at 1500x1500 px
l - save preview image/current image at lower, current screen resolution

Aside from your preview image at 1500x1500, you can generate new iterations at custom resolutions:
(同じスタイルで新しい画像を作成できます。)
1 1500x1500 [generate new iteration]
2 2000x2000 ...
3 3000x3000 ...
4 4000x4000 ...
5 5000x5000 [20-25MB file]

Deterministic generation by PRN + keystrokes.
Example cases/例:
[1]->[1]->[2]->[5] will always generate the same 4 unique images after first load.
[s (save preview)] -> [1] -> [2] -> [3] will generate a different set of 3 new images
