We were asked to come up with a cool idea to recognize the doctors because of their efforts. We offered creating a big photo-wall, where we would take pictures of each doctor, and it would automatically appear on a big video-wall screen. Pictures appeared large at first, to fill the screen as fast as possible. And as more and more pictures came in, all of them were reduced in size to accommodate more. We also had to make sure the pictures followed a pre-defined pattern without obstructing it. It was a nice mathematical and programming challenge!
