graffiti.moe is a public wall you spray a short line onto from the browser — up to 1,000 characters, color and bold optional, ASCII art welcome. curl graffiti.moe pulls one back at random in plain text, and brew tap ttscoff/thelab && brew install graffiti puts a native client in your terminal for a shell startup file. Maker Brett Terpstra calls it “fortune cookies with spray paint,” his spin on the old icanhazdadjoke login trick — except the lines come from whoever shows up.
