After his reaction on 7x13, I decided to put this together for him. What delayed it so terribly (and yet in time for the holidays) was, again, the rendering. Set it for 1024 samples, rendered 3 times for the 3 layers, and may have spent over a million Sheep-it points.
Not especially happy with the animation, but because I couldn't watch it in real time, I never saw the problems.
During this render, I was in Scotland to watch the Military Tatoo, and at the end they happen to sing Auld Lang Syne, which I engaged in the "mile long handshake". It was fun.
Song: Daniel Ingram - Days Gone By Sung by Applejack (Ashleigh Ball), Applebloom (Michelle Creber), Granny Smith (Tabitha St. Germain), Big Macintosh (I heard a male voice in there), Applegeek, and Phoenix Chamber Choir. From the album It's a Pony Kind of Christmas
