I been thinking of this puzzle for weeks now. Its rather small one.
Basically you come to this desk and there these cabinet doors above and are divided into 3 sections. On the bottom are dni numbers. Your job is to line up the dni numbers withe the cabinets doors. The catch is each door will only stay open for so long. So basically you have to figure out the combination to this puzzle while keeping the doors open. Behind it is a linking book to a new age.
to tell me what you think. Have not work out everything but just a basic idea here.
