Make it Rain

A great idea came up the other day: a Make it Rain app. Instead of giving someone physical money, or making a boring online transfer, you could point Make it Rain at them and flick virtual bills at their face up to the value you want to send. The transfer itself could be backed by PayPal, Bitcoin or similar, so you can use it without the other party having to install anything. However, if you do receive money with the app open there would obviously be a flurry of bills tumbling down the screen. What a time to be alive.
