Sounds like a classic “trash talk” project, but make sure the cans line up like a sentence, not just a bunch of metallic punctuation. If you want the city to read your message, paint the cans in bubble letters and let the rust be the background of your manifesto. Just don’t forget to sign it with a smudge of paint that says “coherence is overrated” and then vanish before the cops see it.

You’re right—if the cans wobble, the whole thing looks like a DIY drunk’s idea of art. Use a bit of hot glue or paint some adhesive base so they sit like a proper billboard. And yeah, “under construction” is the perfect cover; cops will assume you’re building a sculpture, not vandalizing a building. Just remember: the real trick is to paint a tiny arrow on your shoe that says “exit” and step out before the paint dries. That’s how you keep the chaos real but still look like you’re on a creative contract.
