Colors2014 Winner   
By Gustavo Almeida, Adriano Otuka, Emerson Barbano, Renato Juliano Martins, Nathalia Tomazio, and Franciele Renata Henrique, Universidade de Sao Paulo, Sao Paulo, Brazil

Our video explains how screen devices produce the colors we see. We introduce a few information of the transition from black and white TVs to colors ones and ask the audience how many colors screen devices are able to reproduce. With three LEDs we demonstrate the RGB additive method and recording cell phones screens under a microscope we show real devices working. Then, we say that a pixel is able to produce around 17 million colors.

Optics, the Heart of High Speed Worldwide Communications2013 Entry   
By Clément Javerzac-Galy, Ecole Polytechnique Fédérale de Lausanne and Institut d'Optique Graduate School, France

All kinds of optics are hidden behind your laptops and phones. Everytime you exchange information, it is processed by optical technologies. This is what we try to show in this video; the contrast between the simplicity of sharing data with a phone and the beauty of the optics that actually enables it. We used all our passion for optics in this video trying to emphasize how optics interconnects the world. We finally try to give glimpses on the future of (green/all optical) communications.
