grapcha
grapcha is a captcha generator based on Graphviz. It produces diagrams that are big and easy to read by humans but hard to break with bots. A person reads the diagram by starting at the green "diamond" and stopping at the red "square", while ignoring the eventual random padding at the beginning and end for short texts.
