And the award for Most Unnecessary Signage goes to...

This. As Rain Noe perfectly explains on Core77, "the entire point of [the two symbols] is that they don't require an explanation and can be understood by those who cannot read English."

I'll be so lost in puzzling over all this that I might just ignore the steady red hand and wander into the street!
