I know this is old - first done back in 2014 I believe. I updated it in 2016 by adding the smoke to the chimneys. Anyway here it is on the new forum - just to add a little Christmas cheer.
You can also change the volume of the music Up or Down with the “u” and “d” keys, and if you, for what ever reason, would rather have no music, it can be toggled On/Off by hitting the “o” key. The camera speed can be made slower or faster with the “s” or “f” keys.
Enjoy your Christmas . And as for the sign by the big Christmas tree - do what you can.
