This is a truly fascinating read. It was linked in the other story about OS/2, and I couldn't stop reading. Apparently it will turn into a book, looking forward to buy it!

    Author’s note: The Demo Scene is the latest piece in a
    long-running Ars series on the history of the Amiga. The last
    installment in the series ran in 2008, but professional
    obligations for the author caused a delay. More chapters are on
    the way—emphasis on chapters. The ultimate aim is to compile all
    the parts of this series into a book. Stay tuned!
