 [ Notes        ]
 
   Original music by Krystone

   4-bit sample playback routines

   Implemented sample playback
   in both forward and reverse.

   Kept sound wave amplitudes
   organized so that both nibbles
   are equal as much as possible,
   in order to achieve maximum
   compression.

 [ Explanation   ]

   Apart from what you see
   and hear, this intro
   actually has a special
   effect that can only be
   observed on CRT displays:

   "The Magic Pulse"

   There's a slight screen
   geometry change when the
   heart is at its peak
   brightness.

   The effect is called
   blooming, and it is caused
   by the high beam current
   affecting the CRT's high
   voltage and magnetic
   deflection. The electron
   gun has to push much more
   current than usual.

   With more beam current,
   there's a slight voltage
   drop, electrons travel
   slower, and the deflection
   coils bend them more,
   causing the image to get
   larger or warped. So...
   the heart pulsates.

   This is the essence of the
   demo. If you didn't see it
   on real hardware attached
   to a real cathode-ray tube
   display, you've missed
   half of the demo.

   On the upside, since the
   picture is mostly static,
   you can try to see through
   it much like with
   a stereogram, a.k.a.
   Magic Eye, which works
   best on progressive
   displays.
