This document introduces the concept of open design. It provides examples of open design projects in various fields such as web design, fonts, architecture, and hardware. Open design refers to projects that can be shared digitally and compiled or manufactured locally. It emphasizes sharing, collaboration, and open licenses. True open design involves a community designing through an open process, not just a single designer publishing a file online. It requires a shift to "metadesign" where the community and process are open-ended.
