Usage

Overview

Buckminster Fuller's map of the Earth projected onto the surface of an unfolded icosahedron. It depicts the Earth's continents as one island, or nearly contiguous land masses.

This screen saver animates the progression of the dusk terminator across the flattened globe. It includes both satellite and flat-colored map imagery, and can load and convert other Equirectangular-projected maps.

Draw on the specified window.

--delay number

Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).

--speed ratio

Speed of the animation. 0.5 means half as fast, 2 means twice as fast.
