I'm watching The Thief and The Cobbler: Recobbled Cut Mark III, which is the an ongoing restoration project of the greatest animated film of all time, which was never finished, about 85-90% done. To make this, all kinds of programs had to be used, hundreds of hours of editing by many people, and even some horribly animated footage for the butchered released versions to tell the story better.
Someone put the entire thing into one video.
And here is the website of the leading person behind this restoration. They are slowly finding more and more artwork and pencil tests, as well as fixing up more scenes, and for the first time, some of this footage will be in HD. The Mark IV edit will come out sometime next year, so please donate.
Here is Garrett Gilchrist's website.
