Projection is one of the things I miss about film. I used to project
my kodachrome 64 slides to great effect. Today no 16 MP digital 
projectors are even available let alone affordable. A nice ektagraphic
slide projector was only a few hundred bucks. The other benefit was
shooting slides was cheaper than prints...

Kodachrome has excellent dark storage stability, but terrible fading 
problems when exposed to bright light. Kodachromes that were projected a 
lot had a habit of fading. IIRC, Henry Wilhelm was able to measure 
fading in Kodachrome after as little as an hour of projection.
Ektachrome, OTOH, had much better behaviour when projected, but some had 
terrible dark storage. My father was an avid slide film shooter, but not 
a great photographer. Perhaps he thought that projecting them bigger 
made them better, I don't know. He made us sit through interminable 
boring slide shows.
But I digress.
The point of this, if I can ever find it....
When we cleaned out my parent's house in 2002, I came across my dad's 
slides, and went through them. All of the Kodachromes were in good 
shape, only showing what I would consider projection fading. A lot of 
the Ektachromes, however, had faded completely clear, and everything 
from when he started shooting Ektachrome in the early 60s was showing 
pretty severe fading. All the slides I was paying attention to were from 
the mid 1950s to the late 1960s.
