It's one of the best commercials that I have ever seen. My dad had a 65 Impala SS. I remember the same sensations that his son described. It was a very cool car. I wish my dad was still alive. It would have been great to find one to restore with him.
On the wrist the effect is subtle. It's nothing like what you see in the macro pics. You really need to play with lighting and angle to see it. Any less texture and it just looks flat.
