On the heels of Airbnb launching their own After Effects-to-mobile animation tool (Lottie), Facebook has their own similiar tool.
It wasn't long ago when this kind of animation was reserved for only the highest end apps or games. Now motion graphics are essential for any native mobile app. I remember back when I was working on Google+ and Fred Gilbert was pushing the envelope for more animation in the product, in coordination with the Google Search and Material design teams. Things have come a long way since then — so much so that these open source projects are now used as top-of-the-funnel recruiting mechanisms.
Incredible.
