I want to render surfaces semitransparent to let other graphics underneath  
shimmer through.

I did try to use the Prolog and Epilog to call the postscript operator  
setalpha, e.g., 

Prolog->PostScript["0.5 setalpha"]

The results are more than strange. The notebook cursor disappears. For  
fully transparent, the surface is totally black. 

Are there other ways to achieve the desired result?
