It’s the “take it, break it, remix it, no lawyers will chase you” license.
Legal‑speak: CC0 (Creative Commons Zero) is a public‑domain dedication. The creator waives all copyright, so anyone can copy, remix, merch, tattoo, or 3D‑print the art without permission or credit.
Crypto‑speak: “Right‑click‑save & do whatever, ser.”
Why artists use it: Maximum meme‑spread. Your work can roam the internet unfenced, gathering culture points (and maybe pumping your other pieces) instead of gathering dust behind DRM.
What it’s not: A guarantee of royalties, attribution, or good taste. Once it’s CC0, the universe owns it—and the universe has questionable design skills.
So when you see a project brag, “We’re CC0,” it means the art is liberated. Fork it, slap it on a skateboard, turn it into a GIF with Comic Sans—no permission slip required.
