We have put together a very special Flickr group showcase , our second of 2013 with some of our favorite images submitted this week. The quality of submissions continues to rise every week, so we have decided to make our showcases that much bigger to incorporate as much of this stunning mobile art and photography as we can and to get it out to a wider audience.
