   XtalView can do this.  You would need to calculate Structure
Factors with sfcalc, and then use xfit or xfft/xcontur to display 
the density.
  
   XtalView is available by anonymous ftp from CCMS at the San Diego
Super Computer Center.  Send e-mail to ccms-request at sdsc.edu with a 
blank subject and the line "get xtalview".  Instructions will be 
return mailed.
