The same sky from both ends of the Earth. Each dial keeps your local time and shows the real stars, Sun, Moon and planets. Open either one full screen on your display.
On a display. Open a dial's address in the browser on the player and tap once for full screen. The dial fills the short side of the screen on pure black, so the unlit pixels stay off.
On an LED controller that shows a fixed area of the video output, set the exact size and position, e.g. /display/crux.html?size=400&x=0&y=0 for a 400-pixel disc in the top-left corner.
Other options: ?tz=8 sets the UTC offset if the player runs on UTC, and ?stats=1 shows the frame rate and the time each update takes.
Offline: both dials as stand-alone files, with instructions: download the kit (ZIP, 177 KB). No installation and no internet connection needed.
