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

From crates.io, once published:

cargo install cyber-rain

From this repository:

cargo install --path .

Or run it directly:

cargo run --release

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.

Examples

cyber-rain --palette rainbow --message "wake up neo"
cyber-rain --palette amber --density 0.55 --speed 3
cyber-rain --ascii --seed 42
cyber-rain --calm --fps 30 --density 0.4

For a deterministic demo recording:

cyber-rain --palette cyan --seed 1999 --message "follow the white rabbit"
