I've looked closely, and I was wondering how he got the "leverage" to make the chain curl using laces...you can't just thread it through the chain and expect it to work. I tried making a hand using toggle bolts, it's the same concept, but when you try to run a "tendon" through the joints, it won't work. Rather, you need outer braces along the fingers located in between the knuckle joints. Look at the vid again, pause it if you need to and you can see the wire braces on the outside of the fingers.
