Original Description:
This example of 3D uses animated movieclips to make up the sides of the box shown. This methods uses a type of skew operation to fit clips within a psuedo 3D plane so it allows bitmaps and any other kind of Flash imagery to be used for polygon textures or whathaveyou. What this implementation does not allow is perspective. Nevertheless its effects can be inspiring.
I tried to make it fairly easy to customize should you want to use it somewhere else. Just edit the sides and modify the script as needed. It has a few "features" built in but they can pretty easily be taken out if undesired.
Move the mouse to rotate in space. Click and hold the left mouse button to lighten up the interior.
