And not to forget what looked good in 1986 might not look as impressive 
20 years later.  Computer graphics (color depth and resolution in this 
case) have improved somewhat in that time.  Our expectations have a 
definite impact as to how we perceive images.  I remember seeing my 
first "photographic" image on an Amiga using it's hold-and-modify mode. 
 I was blown away.  You wouldn't look twice at it now, except perhaps 
to be annoyed by the interlacing.
