A former jet-propulsion engineer for NASA has just raised the stakes on the novelty Christmas jumper - he's designed a range of pullovers incorporating smartphone displays to digitise festive patterns. 

Digital Dudz seamlessly incorporates smartphone displays into the design, by creating fireplaces with animated flames that will keep people staring at your chest all evening. The jumpers have a special pouch in which a phone running an app is placed, to draw envious looks for about five minutes, and accusations of notions thereafter.

After launching with five jumpers last year, there are now 10 different patterns to choose from, including a Santa Claus stuck in a chimney and a glowing Rudolph's nose. The jumpers retail online for €50.

In the battle for domination at your office Christmas party or out doing the 12 pubs with friends, the Digital Dudz make for one easy way to win the Christmas showdown - while always knowing where your phone is. Check out the video below:
