Smart People, Ahoy!

So you think you're smart? And by this I mean really, really smart?

Try giving this a gander. It's a puzzler called Petals of The Rose, and if you figure it out you get to be part of a select group of people who know how it works, including Bill Gates (whose encounter with the game is the stuff of legend) but you're not allowed to tell anyone, you see, because honestly, where's the fun in that?

I foresee a lot of head scratching today.

Thanks to boingboing for the link!
