You may or may not have already come across Glen Keane's latest short, Duet, which has been doing the rounds since its reveal at Google's I/O conference earlier today. This was produced as part of the ATAP shorts series - a collaboration between Google engineers and animators, who work together to produce a new type of interactive short film (I guess you could call it that) where viewers use their phones as interactive windows into the world of the story.
Wow, I really love this. It's a really captivating and beautiful piece. There's just something really soothing about the smooth flowing shapes, and that unmistakable pencil-on-paper "Glen Keane" look. It's often when looking at hand drawn animation like this, that, as a CG animator + developer of software for doing so, that I get inspired to think again about the tools we have at our disposal, and specifically how we could wring more expressive flexibility out of them.
