@rickydazla - it's just an extra shadow to add quality to the effect.
I wrote a sass implementation for whoever needs it, as the link mentioned above is dead.
@mixin shadow($depth){
@if $depth == 1 {
box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24);
} @else if $depth == 2 {
box-shadow: 0 3px 6px rgba(0,0,0,0.16), 0 3px 6px rgba(0,0,0,0.23);
} @else if $depth == 3 {
box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);
} @else if $depth == 4 {
box-shadow: 0 14px 28px rgba(0,0,0,0.25), 0 10px 10px rgba(0,0,0,0.22);
} @else if $depth == 5 {
box-shadow: 0 19px 38px rgba(0,0,0,0.30), 0 15px 12px rgba(0,0,0,0.22);
}

@gefangenimnetz can you elaborate on why you chose the values you did? The result looks nice but I am looking esp. at the second values for v-shadow and blur.
The pattern in the first set of values is pretty clear but the second set isn't. Just curious..
