This is cute and might work around the house, but I wouldn’t entrust anything serious to it. As soon as your traveling and don’t have it, or your kids rearrange it, or someone else gets a picture of it, then it the novelty is definitely gone. You could just as easily use a deck of playing cards or to construct a password and it would have exactly the same issues. Yubikeys win the day again and again, I just more sites support them. The financial sites that would benefit most are still stuck on easily spoofed SMS authentication - if they even have that.
