I had this weird idea a while ago: What if there was one place on the internet where everyone could simply say “I was here”? So I built The World Wall. You enter, write your name or a few words (you can even draw your signature), and you get a permanent number on the wall. Every new person takes the next spot, so the wall keeps growing over time. No account. No email. Just leave your mark and move on. Right now people from 106 countries have already left one. 🌍 https://the-world-wall.com/
