@@BACKFLIP   SG 
(Comp.sys.hp48) 
Item: 1413 by randyd@csd4.csd.uwm.edu 
      [Randall Elton Ding] 
Subject: BACKFLIP animation, SX & GX versions. 
-- slight modification of program originally by 
   Doug Cannon 
 
DON'T RUN 'GOSX' ON A GX, instead delete it and use 
'GOGX'. 
 
[Note: The SX version is superimposed on the stack 
 display, which looks really cool, and is exited by 
 pressing ON.  The GX version is exited by pressing DROP 
 (backarrow); if a lot of keystrokes are in the buffer, 
 it may take a long time to exit, so press ON to empty 
 the buffer and then press backarrow and wait for one 
 backflip to finish.  Both versions use + to speed up and 
 - to slow down, but it's incremental, one keystroke per 
 backflip, so be patient.  -jkh-]

Press arrow keys to control rotation speed.  Initially, 
the four keys push the *far* side of the cube in the 
direction of the arrow.  Each press accelerates the spin. 
 
Press back-arrow to exit to credit screen; then ON exits. 
@@GUTS       SG 
Guts, by Chris Campbell. 
 
Guts is a little User RPL program that fills the screen 
with a random tunneling pattern that bears some 
resemblance to its namesake. It's not very fast, but 
it's not all that big either, and it's fun to watch! 
 
[Nasty tip from my students: beam this into your friend's 
 HP48 with a control alarm that'll run it after a few 
 minutes.  Makes 'em freak out!  -jkh-] 
@@HULA       SG 
12-frame movie of a girl using a hula hoop, by Erick 
Hammersmark. 
 
      This is a bit of video I converted from an MPEG. 
The animation is of a girl using a hula hoop. The 
quality is not great, but it looks pretty good if you 
hold it at arms length.  :-)  I can make more of these if 
there is interest, and will happily describe the simple 
process to anyone interested in doing it themselves. 
 
      Included in the directory are:  the 12 GROBs that 
make up the animation;  ANIM by Carl Robert Gibbons, for 
viewing the animation on an S(X);  GO, to start the 
animation on an S(X);  GOGX, to start the animation on a 
GX. The difference between GO and GOGX is that GOGX uses 
the ANIMATE command instead of Mr. Gibbons' ANIM. Note: 
I have altered ANIM to disable the ticking clock display 
while the program is running;  having the clock enabled 
causes problems when single-stepping through an 
animation. 
 
[Exit the SX version by pressing DROP (backarrow); 
 exit the GX version by pressing ON.  -jkh-]

KNOT and BRAID 
By John G. Stebbins 
CompuServe 75320,3000 
August 29, 1993 
 
Each of these HP48 files is a directory containing an 
example of the HP48GX's parametric ploting functions. 
These examples were inspired when I looked at the example 
in the built-in 'EXAMPLES' directory and was quite 
disapointed. I decided to try something more challenging 
and came up with these two equation sets. 
 
KNOT is a torus that loops back on itself and is tied in 
a simple overhand knot. BRAID is three cylinders twisted 
together in a standard braiding pattern. 
 
Each directory contains a list of the GROBs for the 
animation and a program called SEEIT which runs the 
animation. 
 
Also in each directory are the programs, equations and 
settings variables used to create the animation. 
 
For compatibility with the HP48SX the SEEIT program 
determines whether it is being executed on a GX or SX and 
either uses the inbuilt ANIMATE function on the GX or the 
program ANIM inlcuded in both directories. 
 
To exit the animation on a GX press the ON key, on an SX 
press any other key.

USA by Joe Horn, for HP48 S/SX/G/GX 
A Tribute to Betsy Ross and Francis Scott Key 
 
Written as an example of the power of the software on the 
Goodies Disks. Using just a PC and an HP48, this program 
was completely written, from conception of the idea to 
the final product that you see and hear here, in just 20 
minutes. 
 
Press ON when you're ready to sit down. 
 
Not really an animation... but long may it wave!  -jkh-
