    .from(".sliderText",{scale:1.5, duration:1, ease:"back", opacity:0},"<.5")
    .from(".smallIsland",{scale:.1, duration:1, ease:"back", opacity:0},"<.5")
    .to(".smallIsland",{y:15, repeat:-1, duration:3, yoyo:true},"<.5")
    .from(".gramedisland",{scale:.1, duration:1, ease:"back", opacity:0},"<.5")
