This is a spectacular project by Diana Smith:

Rules I have for myself:

1. All elements must be typed out by hand
2. Only Atom text editor and Chrome Developer Tools allowed.
3. SVG use is limited, and all shapes can only use hand-plotted coordinates and bezier curves - without the aid of any graphics editor.

The results are stunning, to say the least. I won’t embed the image here, because it won’t do it justice. You have to click through and see it for yourself.
