var smokyBG = $('#wavybg-wrapper').waterpipe({ //Default values gradientStart: '#000000', gradientEnd: '#222222', smokeOpacity: 0.1, numCircles: 1, maxMaxRad: 'auto', minMaxRad: 'auto', minRadFactor: 0, iterations: 8, drawsPerFrame: 10, lineWidth: 2, speed: 1, bgColorInner: "#ffffff", bgColorOuter: "#666666" }); Options
