- <p>Last year I did the <a href="http://academy.cba.mit.edu/2013/students/rees.john">Fab Academy</a> in <a href="http://fablabbcn.org">Fab Lab Barcelona</a> and I really fell for the city. Since then, together with my trusty dying macbook, I've been whizzing backwards and forwards between European cities in an effort to pursue some sort of 'digital nomadic' lifestyle.</p>

- <p>I chose to enter this competition because I love playing with arduinos and have fond childhood memories of moving the little turtle around in LOGO. So the Arduino Robot seemed like the perfect fit!</p>
