Isometric cityscapes, patterns and geometries generated by trigonometric functions and rendered as SVG.

The SVG can be saved by pressing "s" on the full-screen view.
A PNG version can be exported by pressing "e" on the full-screen view.

By default the dimensions of the export are 6000×7500.
These dimensions can be changed by adding, for example, ?w=12000 to the full-screen page URL, where w is the desired width. Then press "e" to export at this size.
