I always find myself giving props to Vivienne Tam, whether it be for her innovative line of HP Netbooks or her collaboration with Monster for fashion forward In-Ear headphones – the lady is a pioneer when it comes to fusing fashion and technology. Well she is at it again with her designer take on Square. Square is the new gadget from Twitter founder Jack Dorsey that will allow you to take payments via your iPhone, iPad, or Android smartphones. It’s perfect for on the go business people who want to quickly get deposits or payments without having to wait for a check to clear. Tam has taken the Square and transformed it from a plain white ‘Square’ into a piece of Chinese art. The design represents Vivienne Tam’s signature Chinese character – Double Happiness. Which seems appropriate, since it will be money you are getting if you use this device. The limited edition square will be at AHAlife and will make its debut on 2/21/11 it is also currently available at Vivienne Tam’s own website for $10. Besides being trendy; with every purchase 20% of the proceeds will be donated to the Happy Hearts fund started by Petra Nemcova. The charity donates money to re-builidng children’s lives after a natural disaster.
