I like that there's an open area in the middle-left somewhere, and every time you want to get to the shelves you have to hop over hundreds of dollars of cards. You probably get tempted to put cards in that area shrinking its size down so that you have to be more and more precise each time you hop to it. By the time you get an intervention you will be an olympic-level gymnast who can hop onto a dime. You win gold. The End.
