Few days ago, I saw one of the wifi routers around. Ah... saw another router hanging at another bus stop. With hints from the notice there, I found out it's the ShuttleNet project by the Communications and Internet Research Lab at the School of Computing, NUS.
It's dangling very dangerously isn't it?
