The news was revealed by Mark Shuttleworth during a community question and answer session earlier today.
Asked by us whether Ubuntu 13.04 would see changes to the default look and style of Ubuntu, Shuttleworth replied:
"Yes. We have hired the amazing Matthieu [James], which means we can start the icon project.”
James’ squared Faenza icon set is one of the most popular third-party icon sets on Linux, having been downloaded 661,689 times from its DeviantArt page alone.
