...Inspired by the original Ruby “lolcat” project, it takes input from stdin or files and outputs the same text with colorful ANSI escape codes. It’s frequently used to add a playful touch to logs, help messages, or shell scripts, making otherwise mundane terminal output more fun. Options allow customizing color spread, speed, and randomization to create different rainbow effects. Lolcat is often piped into commands like cat, figlet, or fortune to create whimsical and eye-catching console art. Despite being lighthearted in purpose, it demonstrates the use of ANSI codes and stream manipulation in a clean, portable way.
