[away3d] Make a mint moped

[Albinal]

Hi, I've not long finished this:
http://www.albinal.co.uk/moped/

I say finished but really I'm 99% done pending any useful feedback.
So, what does one think?

While I'm here I want to move my Away3D knowledge to the next level...
animation. I'm pretty proficient with Blender and can model, texture,
rig and animate... I see that the Collada exporter has a button for
"sample animation" but where do I start?

I read this: http://away3d.com/index.php?s=animation&x=0&y=0

...but I'd rather not do my animations in the code. I had an
experiment with this and a simple cube rotation:

var skinAnimation:SkinAnimation;

function onLoaderSuccess(event:LoaderEvent):void
{
        var target = ObjectContainer3D(event.loader.handle);
        skinAnimation = (target.animationLibrary["default"] as
AnimationData).animation as SkinAnimation;

        skinAnimation.loop = true;
        skinAnimation.start;
}

But nothing happened?!? I can trace skinAnimation.length and it
returns 0.4 so something is there but many code combinations later I'm
no further down the line.

Any help gratefully received.
