💀 skulloop — the one where we descend recursively into a Platonic unit skull (yes, that's really the manual name, it's skulloop from the XScreenSaver manual and it's kind of iconic) 🎀

🌸 SYNOPSIS 🌸

skulloop [--display host:display.screen] [--visual visual] [--window]
         [--root] [--delay number] [--speed number] [--wireframe] [--fps]

✨ DESCRIPTION ✨

okay so. recursive descent into a Platonic unit skull. that's it. that's the whole thing. bestie it literally says it right there and honestly? it ate. 💅

💖 OPTIONS 💖

  • --visual visual — tells it which visual to use, bestie. legal values are the name of a visual class, or the id number of a specific visual (and that id can be decimal or hex, we contain multitudes 🦋).
  • --window — draws on a newly-created window. this is the default, so if you just vibe and don't pass anything, this is what you get. 👑
  • --root — draws on the root window instead. main character energy, entire screen.
  • --delay number — per-frame delay, in microseconds. default: 30000 (that's 0.03 seconds). so yes, microseconds, not milliseconds, read it again 😭
  • --speed number — animation speed. 2.0 means twice as fast, 0.5 means half as fast. math slay 🧮
  • --wireframe | --no-wireframe — render in wireframe instead of solid. skeleton mode vs. full body, pick your fighter 💀
  • --fps | --no-fps — whether to show a frames-per-second display at the bottom of the screen. little number go brrr, aesthetic, lowkey necessary for vibe checks 🌈

🦋 ENVIRONMENT 🦋

  • DISPLAY — used to get the default host and display number.
  • XENVIRONMENT — used 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.
