Unless I’m mistaken, I think these spots for Helio’s “Ocean” phone came out some time back, but I never really heard anything about their creation. Maxon just recently put up this page, discussing a little about the back-story while plugging C4D of course. I was impressed to find that Grégoire Poget did about 90% of the work, including character design, modeling, texturing, post and even sound and audio. Not an unfeasible task by any means, but certainly a change of pace from a more traditional pipeline workflow.
