You could show a "loading" .gif until your KineticJS project gets running
Just layer a loading.gif under your canvas.
Then when your project is loaded, remove the gif.
Here's code and a Fiddle: http://jsfiddle.net/m1erickson/YaU8W/
<!doctype html>
<html>
<head>
<link rel="stylesheet" type="text/css" media="all" href="css/reset.css" /> <!-- reset css -->
<script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
<style>
#wrapper{
position:relative;
width:200px;
height:200px;
}
#canvas{
position:absolute; top:0px; left:0px;
border:1px solid green;
width:100%;
height:100%;
}
#loading{
position:absolute; top:50px; left:50px;
border:1px solid gray;
}
</style>
<script>
$(function(){
// Load your KineticJS project
// After your KineticJS is loaded, remove loading.gif
// var element = document.getElementById("loading");
// element.parentNode.removeChild(element);
}); // end $(function(){});
</script>
