They’ve just come back from France where, together with artist Liu Qiangyuan, they created an online project called: Only City
About their city of the Eye:
“Only city.org is a city constructed on Google Earth (…)by Yah Lab. They named the Only City “the City of the Eye” in Chinese which implied the capital city/the Forbidden City. Moreover, in Chinese culture the eye is the finishing touch an artist makes his work alive, It is the crucial action that gives life to anything. (…) Liu’s [Qiangyuan] real size woodcut figurines reside in the Only City and become a reflection as well as storyteller(…)”

Using Google Earth (which you could definitely call public space) they’ve created and environment where people from all over the world can connect. Woodcut characters made by Liu Qiangyuan, mix with the virtual world of games and online environments. Here are some screenshots of the site. Click on the thumbnails for larger version:
