Hi,

try opening /js/scripts.js and remove or comment this bit:

// Tilt Showcase Wrapper
var maxTilt = 1.5;
var mouseX, mouseY;
$(document).on("mousemove", function(event) {
mouseX = event.pageX;
mouseY = event.pageY;
});
$('#showcase-tilt').each(function() {
var thisWidth = $(this).width();
var thisHeight = $(this).height();
var thisOffset = $(this).offset();
$(document).mousemove(function() {
var horTilt = ((mouseX / thisWidth) * (maxTilt * 2)) - maxTilt;
var verTilt = (((mouseY - thisOffset.top) / thisHeight) * (maxTilt * 2)) - maxTilt;
TweenMax.to('#showcase-tilt', 1,{rotationY: horTilt, rotationX: verTilt, scale: 1.05, ease:Power1.easeOut});
});
});

there are two: one for the showcase slider and another one for showcase carousel.

Hard refresh the page (Ctrl+F5) to see the changes
