swf_labelframe
You can really do stunning 3D effects using swf_lookat() [and swf_ortho, of course].
Here is a little example of doing a simple 3D-rotation around a text.
The Text is split up into 2 parts, because Flash does not (yet?) support perspective-skewing, only rotation, 2D-skew and scaling. But if you split your 3D-object up into several parts, each part is transformed seperately and you can trick around that loss of perspective-skew.
Have a lot of fun experimenting with that piece of code!
