Red Giant hits it out of the park again both in execution and explanation. Both of these videos are art pieces on their own, I do reccomend watching both. His commitment to virtually replicating traditional animation and even drawing methods really pays off in that it does seamlessly merge with today's graphics and compositing tools. I would absolutely watch a short or full length film in this style.
If nothing else, let this be a reminder that sometimes playing the long game is well worth the effort.
And don't forget to watch the making-of video on Stu's website.
