In fact, while I'm here I may as well pick your brain! - Some other libraries when you invert values it changes direction. Is there anyway to do direction with this? So say two lines go up and one goes down? Would be super useful to have a "direction" attr or something similar for when you want to quickly achieve this along with the parallax effect.
smoother.effects(".hc1", {speed: 0.5, lag: 0.5, direction: -1});
smoother.effects(".hc2", {speed: 0.5, lag: 0.5, direction: 1});
smoother.effects(".hc3", {speed: 0.5, lag: 0.5, direction: -1});
