For the lazy: the symbol (⌘) has apparently been used at Swedish campgrounds and parks for decades. It's used to denote interesting features, both natural and man-made. It was inspired by the way Swedish castles look from above (a central building with a turret at each corner).
Our bitmap artist Susan Kare had a comprehensive international symbol dictionary and she leafed through it, looking for an appropriate symbol that was distinctive, attractive and had at least something to do with the concept of a menu command.
Finally she came across a floral symbol that was used in Sweden to indicate an interesting feature or attraction in a campground.
Apparently it started being used to denote a place of interest in Finland in the 1950's. Funny enough I have always thought that sign was universal, understood by all culture to mean you can park your car here and see something interesting.
I've also met some Indian guys who bob their head when they're in agreement which is very similar to how I'd be used to people I know shaking their heads in disagreement.
I see that as a kind of figure-of-8 movement... when my friend and I visited India we decided that it was a cross between a nod and a shake ie. ambiguous yes/no, non-committal

That's not how I know the sign. The Swedish Transport Agency has a page for this road sign[1].
It says, roughly translated: “The symbol indicates an historic site [or attraction] of national interest. The nature of the historic site is indicated in connection with the symbol.”
So, it's probably more commonly used to mark viking age burial grounds than campgrounds.
