Last week I attended Microsoft Austria's Big Days 2008 and found out about the contest - two nights of coding later, and Captain Alex (namesake of my older son) reached the top position. Captain Ahab, the old swashbuckler, is still a tough competitor though.
And by the way kudos to Cubido. What a great idea! This is the kind of stuff that excites most software developers. And their Silverlight client does have really cool visuals.
I am going to blog about the algorithm once the contest has ended (it is quite simple).
