For you, no animations? skip the reel. HR people are busy, best to make an awesome first impression on them with some amazing stills as soon as your page loads. From what I understand HR people don't like to bother with reels (unless looking for animators of course), if they don't like what they see on your site then it's…
I've only used CompositeMode so far, it handles two at a time but you can layer them, so like this: <font class="small">Code:</font><hr /><pre>CompositeMode map Bitmap1 (additive) CompositeMode map Bitmap2 (multiply) Bitmap3 (normal)</pre><hr /> Hope that makes sense. You'll see when you get in, it's pretty cool.
