To be precise this is DevArt with Google - see https://devart.withgoogle.com - so the programmatic creativity involves open source and Google-friendly technology (such as Chrome apps and using the Google Compute Engine, in the winning entry).
The company writes:
DevArt is a new type of art. It is made with code, by developers that push the possibilities of creativity and technology. They use technology as the canvas and code as the raw materials to create innovative, engaging digital art installations.
The compo has now closed and Google outlines some of the entries it received (you can follow the links, and see even more on its dedicated DevArt page):
Mapping a dream as it navigates through your brain using G+APIs. Exploring metamorphosis through storytelling in the form of a poetic adventure with Chrome Apps and Compute API. Travelling through a playful giant map that explores fantasy and reality on a huge scale using Map API. Creating music through the touch of your finger on a simple piece of wood using Android.
The winner of the £25K prize? A French duo, Cyril Diagne and Béatrice Lartigue, who present Les métamorphoses de Mr. Kalia, an "interactive poetic adventure around the theme of metamorphosis in the human body".
