    Rainer Joswig has made another video [...] demonstrating what it's
    like to use a lisp machine. I think this one gives you a better
    sense of what it's like in day-to-day use, and why it was such a
    productive environment that people are still obsessed with these
    machines decades later.

 * rainer-lisp-machine-3.mov is a short video 
 * rainer-lisp-machine-3a.mov is a non-MPEG4 version of the same thing
 * lispm-2.mov is a longer film, showing the editor, document examiner,
    listener, dynamic windows and presentations
 * lispm-2a.mov is lispm-2.mov,  non-MPEG4

Most people have eventually found that viewing these in Linux is possible
somehow, but no two people have had quite the same experience.  For
me, I found that xanim did the trick but mplayer wouldn't.  It's a
"1-bit RLE Animation" Quicktime file with audio.  Make sure you get the 
sound working, it's a bit difficult to understand what's happening 
without the voiceover
