Photos: Microsoft's Imagine Cup finals

Microsoft last night crowned the winner of its global developer competition, the Imagine Cup; an annual technology competition that pits student projects from around the world against each other. The projects fall into the categories of software, cloud computing and game design, with an emphasis on solving some of the world’s most pressing problems.
This year's worldwide finals were held in Sydney Australia, where more than 350 contestants from 75 countries converged for the final leg of the race. We take a look at some of the most interesting projects on the showroom floor.
