Pirate Themed Room

I'm not a huge fan of rooms that are this themey but when I saw this nursery on {Design Dazzle} my mind started racing.
It's a total Pirate nursery, which is fine if you like themes. But what really got me was this ceiling:
Yeah, it's a treasure map.

How creative is that! It really got me thinking about playrooms. I mean, you could paint a floor like this in any playroom and it would be so much fun - and probably a lot cheaper than any other kind of flooring out there. Little boys would love this.
