Call for Entries: CDN-GM Interactive Design Competition 2012

With temperatures soaring across North America, there's no better time to hunker down in an air-conditioned room with your pen, vellum, and markers (or, more realistically, your computer and tablet) and get working on your entries into the GM Interactive Design Competition 2012.  It's only been a month since the official launch of the 2012 GM Interactive Design Competition and we're already seeing strong participation and a very high level of quality for the entries. Open to all full-time college or university students from across the US and Canada, this competition is a great way to gain exposure, but also to keep up and improve your skills over the summer. With five paid internships (housing included) at GM's studios in Warren, MI up for grabs, there's no better launchpad for your career in the automotive industry, and getting your entries online early also gives you a head-start on the competition by allowing the public and mentors to critique and review your work.
