	This directory contains an image sequence suitable for animation
	with animate.  It was created like this (Danielle, 4/25/91):
	
	1) % viewimage -i $KHOROS_HOME/data/images/feath.eye 
		       -e $KHOROS_HOME/data/images/flow.eye
	   i used the Perspective subform to get a Top view of the image
	   data, and used the Attributes subform to get a surface plot, so
	   that the imagery in feath.eye was seen from the top.
	   then i went back to the Perspective pane.

	2) then, for each frame of the first 30 frames in the sequence:  

	   a) i incremented the alpha and theta perspective values by
	      1.0 and waited for viewimage to redraw the imagery draped
	      over the elevation data

	   b) % getimage -o eye.num -e
	      where num was equal to the current value of alpha & theta
	      to get a VIFF image from the displayed data.

	   c) % vextcent -i eye.num -o eye.num -w 500 -h 500
	      since as a human using the rubberbanding method, i am not
	      precise enough to make each image 500 x 500, and they must
	      all be of the same size

	   d) % vmapdata -i eye.num -o eye.num
	      to remap the image data to get a linear 'grey scale' colormap   

	   e) % vshrink -i eye.num -o eye.num -s 2
	      in order to cut the image sizes in half so as to be better
	      for use with animate

	   f) % vbandspt1 -i eye.num -o eye.num
	      since vmapdata creates a 3-band image, and i only wanted 1-band
	      images for use with animate

	   { Note: steps (c - f) performed with a shell script, after all the
	           images where created in steps (a - b) - i'm as lazy
	           as the next person }

       3) then, each of the last 30 frames in the sequence was copied from
	  the first 30, in backwards order
       

       4) finally,  % vbandcomb -base eye -o eyes
	  combined all the single-band images into one 60-band image
	  called "eyes" for use with animate, and had to remove all the
	  single-band images because we're low on space, and "eyes" is pretty
	  extravagant all by itself.
