okay bestie, welcome to crystal(6) from the XScreenSaver manual — it’s literally a wee kaleidescope situation, and we’re obsessed. 💎✨

💎 NAME 💎

crystal — kaleidescope.

🌀 SYNOPSIS 🌀

crystal [--display host:display.screen] [--visual visual] [--window]

number] [--ny number] [--count number] [--delay number] [--ncolors
number] [--fps]

🌈 DESCRIPTION 🌈

Moving polygons, similar to a kaleidescope (more like a kaleidescope than the hack called kaleid, actually.) 🫶 No cap, that’s the whole vibe.

✨ OPTIONS ✨

okay, the flags, bestie — every single one:

  • --visual visual — Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. 👀

  • --root — Draw on the root window.
  • --window-id number — Draw on the specified window.
  • --grid | --no-grid — Whether to draw grid.
  • --cell | --no-cell — Whether to draw the cell.
  • --centre | --no-centre — Whether to center on screen
  • --nx number — Horizontal Symmetries. -10 - 10. Default: -3.
  • --ny number — Vertical Symmetries. -10 - 10. Default: -3.

psst: the synopsis above also lists --display host:display.screen, so don’t forget it’s in the mix. 💅

  • XENVIRONMENT — to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
  • XSCREENSAVER_WINDOW — The window ID to use with --root.
