As the title suggests, this is the central hub in action. Unfortunately, I had no backups of the old factory settings of the fort. However, you can actively see the stones get cleaned out, and deposited into the mason's shop, food coming from above being fed to 12 O'Clock, gems are to be dumped into it's slot (1 O'Clock), but are being put inside the cart. Blocks and furniture are being sorted as they finish as well. And as you can see, the shops are always stocked, and the halls are cleaned in a jiffy.
With enough dwarves, exchanges of wheelbarrows occur as the stones and etc. get put to their final resting place.
Excuse the buggy appearance. I was using a tileset when recording, and recorded in window mode. It's been awhile since I last used the record function, as you can see.
For best experience, watch at rate 300-400.
