Of course, no self respecting open-source project can be successful without a logo. If you are interested in designing our logo, go for it! Otherwise, we are stuck with that thing at the top of this page.
Email your work to: David Weiss.

A moyo is a large area in the middle of the board, so a moyoman would be a person with a large area in the middle. A Sumo wrestler immediately springs to mind, so one idea would be to have a Sumo wrestler at the Go board, possibly with a Samurai sword as well. Other ideas are also possible. If you have any artistic talent, you are encouraged to use your imagination and submit your idea.
