Cool! I never knew redbull was posting tech news on their website 

Favorite quote from the interview:

Where did the idea for Pigzbe come from?

"I was thinking about my four-year-old son and his future. One day I noticed him talking to my own father on Skype. My father was holding a 2p coin up to the camera: “Your mummy tells me you’ve been helpful recently, and kind to your baby brother. You see this coin? When I come to London next month, I’ll give it to you for being such a good boy. We can put it in with all your other coins, and maybe we can go buy some Lego!” It occurred to me that physical money, especially in its smallest denominations, just isn’t useful for globalised families who communicate digitally."
