This week, David Leach - head of sparks data insight company "Qrious"- joins Vaughn to dicuss what exactly 'big data' is and how everything from phone calls to weather has now become digital.

Phone companies used to only know when you made a call- now, they can locate where exactly you were and can predict who you might be making regular calls to.

David explains there is no shortage of data now- across web, smart phones and devices.

Why is weather now connected to the internet...?

Also, Vaughn is talking to Julian Waters for Apps of the Week.

Paywave is all the rage - waving a credit card to make a transaction... But what about Apple watch? Soon you won't need to carry your phone, keys, and cards but instead just swipe your watch.

BNZ is offering Apple pay soon with apple pay app... Vaughn and Julian discuss if this could extend to loyalty cards (imagine not having to carry those around!)

Also, 3D printers have the amazing ability to print a lot of things. But imagine, a 3D printer that can print... 3D printers?! What other magic can it do!
