[ 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.
