cyber-rain

cyber-rain is a smoother, themeable Rust terminal digital-rain visualizer: falling glyph streams, raw terminal rendering, hidden messages, deterministic demo runs, and enough controls to make your terminal look like it knows something you do not.

Install

With Homebrew:

brew install anthony-cervantes/tap/cyber-rain

From crates.io:

cargo install cyber-rain

From this repository:

cargo install --path .

Or run it directly:

Quit with q, Esc, or Ctrl-C. Pause with Space or p.

Features

• Themeable rain: green, cyan, amber, crimson, ghost, and rainbow.
• Tunable motion with --fps, --speed, and --density.
• Hidden message mode with --message "follow the white rabbit".
• --ascii mode for plain terminals.
• --seed for reproducible recordings or demos.
• Terminal resize handling.
• Buffered terminal rendering for smoother motion.
• Occasional burst storms, or --calm to disable them.
