I was wondering if there is a way to do transparent 
halftoning?  Well, let me explain what I'm doing.
By using PostScript I've already got an image of a
brain displayed.  Now, what I need to do is overlay
a grid of boxes (filled with different gray tones) 
over the brain.  Is there a way to make this boxes 
somewhat transparent so the brain image can still
be seen under the boxes?  Hope thus made sense.

Any help would be greatly appreciated!! 

Thanks,

Jerry
