The latest trailer shown at this year's Game Developer's Conference for the upcoming Legend of Zelda: Skyward Sword was fine at first glance, and had the delightful music gamers have come to expect from the LoZ series. Fast forward to this week, when YouTube user FPAwesome1 showed that if you play the song from the trailer backwards, you hear ZELDA'S FREAKING LULLABY. Applaud the Nintendo mastermind behind this masterfully hidden easter egg. Kudos to you guys. [via Games Radar]
