Ah, it’s definitely working, just a bit subtle.

You can increase the effect with a filter:

add_filter( 'generate_sections_parallax_speed','generate_custom_parallax_speed' );
function generate_custom_parallax_speed()
{
     return 6;
}

6 is the default – the lower the number, the greater the effect.
