Solve the puzzle and you can win money!

The Kuku is driving us cuckoo here at ThinkGeek. We keep passing the shiny metal sphere around the office, but nobody can figure out how to open it. Even our smartest monkeys are totally stumped. There just doesn't seem to be a way to get it open! It's quite possibly even harder than the Isis Puzzle, which we also can't solve. If you want the ultimate bragging rights of being smarter than a ThinkGeek monkey, you need to solve the Kuku (or Isis, or both!) and send us pictures so we might sing your praises and laud you as some sort of shiny brushed metal puzzle deity.

If you ever do make it to the center of your Kuku, you'll find a token that can be registered online to play the vault game. To open the vault, you must decode a picture clue to identify a 10 digit code. The first person to enter the code correctly is admitted into the vault for five minutes. In those five minutes, you explore the three dimensional room and choose a safety deposit box. In the box could be cash, a gift voucher, various electronic gifts, or even a new high quality puzzle. According to the manufacturer's website, no winners of Kuku have stepped forward to claim their prize - will you be the first?
