TECHNICAL INFO:
 name: WALLPAPR.83p
 size: 698 bytes
 platform: ION

INSTALLATION:
 Send WALLPAPR.83p to your ti83.
 You must have installed Ion (downloadable on ticalc.org).
 Run Ion, run "WallPaper 1.0 by TexAmeije" and press [ENTER] to enable
 or disable the interrupt. Press [2nd] to edit the wallpaper.

WHAT IS IT?
 WallPaper is an interrupt program. This means that you can do
 everything you want with your calc while it's enabled. So you can
 use you calculater like you always do, except that there is an 8 by 64
 pixels wallpaper on the right side of your screen. It doesn't affect
 any program or setting on you calc. I made this program to cheer you
 up while you make your exam or when you have a hard time calculating
 something or playing a game... You can edit the wallpaper on-calc with
 a built-in drawing routine.

EDITING THE WALLPAPER
 In edit mode, you can draw your own wallpaper. Press 2nd to put the
 pen down and use the arrow keys to draw. The cursor is an inverted
 pixel when the pen is up, a black or white pixel when the pen is down.
 Use ALPHA to change the color (black/white).
 If you want to start from scratch, press CLEAR to clear the whole
 wallpaper to the selected color.
 If you're ready, press MODE to save and exit to ION. Now, just enable
 the interrupt (=press ENTER in menu) and watch your own wallpaper! If
 it was already enabled, you must disable and enable the interrupt
 again to watch your new wallpaper.

CONTROLS:
 -in menu:
    ENTER = enable or disable the interrupt & exit to ION
    2nd   = edit the wallpaper
 -in edit mode:
    ARROWS= move cursor (=inverted pixel)
    2nd   = put pen up or down
    ALPHA = change color (black/white)
    CLEAR = clear the whole wallpaper to the selected color
    MODE  = save & exit to ION

REMARKS & HINTS:
 -The problem with the wallpaper is that you can't see what's under it.
  This is especially annoying when you the answer of a calculation. The
  solution is to go to the TI-OS MODE menu and select float 3 or
  something like that:
   MODE menu:   <NORMAL> Sci Eng
                Float 012<3>456789   <--- select number 3
                <RADIAN> Degree
                ...
 -When you run heavy programs while Belzeblub swims over your screen,
  your calc will slow a little bit down. Most of the time you just
  dont notice it.
  But think about this: when you play a game whit limited time (think
  and react fast), it could be an advantage when you have this interrupt
  running and slowing down the time! :-)

BUGS/CRASHABLE?
 This program has never chrashed on my ti83, you can do everything
 while the interrupt is running: every function from the TI-OS, all
 basic programs and even ASM has no problem with it!
 But if it should happen to you that your ti crashes (it won't, but
 if..., you never know) please let me know!

Thanks for downloading and admiring Belzeblub

Watch for my other programs:
My best game: Pipemania for ti83
Another interrupt program: Belzeblub
