Fake bank account balance app

You know how in the movies, someone's bank account gets hacked, and they watch their money going down to zero on a monitor / cell phone etc? I want an app that does exactly that: push a button and it looks like all the money is being drained out of your account. There will be some settings where you can enter how much 'money' (this is all fake, remember) you have, let's say $100,000,000.00, and pressing the button 'drains' the account down to zero along with a progress bar and maybe some sound effects. I'd also like it to do the opposite: start with a balance of $0, and push a button that makes your bank account look like money is being injected into it (also with a sound effect). This app is just for fun obviously. The idea being you can joke to your friends that you just got 'hacked' and you watch your bank account drain down to $0. Or pretend you just won lotto and your bank account is filling up with money.
