This Hello Kitty ATM Bank looks way too cute:
"The upcoming Sanrio licensed Hello Kitty ATM Bank features a flip-top lid which pops up to reveal an keypad, a digital readout, and a coin slot which accepts 500-yen coins. Since a 500-yen coin measures 2.65cm or 1.04" in diameter and a USA quarter (0.25 cents) is slightly less than an inch in diameter, the Kitty Bank will store up to 500 quarters. Three styles are on offer for preorder and reservations are welcome today."
...I was going to wish that they made a version just or American currency, but even then it would be a stretch to think that you would use this in the real world (aside from showing it off to fellow kitty fangurls and fanboys).
