Hi  
i have been thru the 3d section for action script based at this site  
and i have made a 3d spinning cube  
[http://www.mn001c7645.pwp.blueyonder.co.uk/cube.html](http://www.mn001c7645.pwp.blueyonder.co.uk/cube.html)  
can someone tell me how to add light sourcing to it  
by that i mean, make each side of the cube go brighter or darker depending on the depth  
like in this example
