I recently ended up writing a small utility that displays images inside the terminal using only ANSI color blocks. It’s not fancy, but it made me realize how flexible the terminal still is — even without GUI libraries or modern frameworks.

Just wondering: do others here still build CLI or terminal-based tools for side projects, retro use cases, or just for fun?

Would love to hear your favorite hacks or experiments.","time":1752585856,"title":"Ask HN: Do you still build terminal tools for fun?","type":"story"}]]
