I downloaded it, and here is what it is:

It's a graphics animation demo for the Apple IIGS.  It uses some of
the trickier animation techniques, such as border color swapping and
palette switching, to achieve some interesting effects.   There are
a dozen or so different demos, including a fake HAM (hold and modify)
mode that is on the lame side.  (HAM is the 4096 color mode on the Amiga).

There are some impressive letter scrolling demos.  The scrolling is very,
very smooth.  Some of the scrolls have interesting expansion effects (kind
of like the letters are being stretched).  The graphics work is very good,
too...good use of color.  There are many variations on the scroll, and some
"sprite" animation demos along with some game-like sequences.  

It appears to use some routines of dubious originality...for example, the
ACS logo swooshing onto the screen looks like a rip-off of the FTL boot on
Dungeonmaster GS.  There is a cheesy Arkanoid screen, with animated shapes
and balls and paddles.

You have to reset to exit each demo...sort of annoying, but perhaps neccessary
to achieve the level of animated fluidity exhibited by these programmers.
