@echo off  
:line 
color 0a
setlocal ENABLEDELAYEDEXPANSION  
 
for /l %%i in (0) do (  
set "line="  
for /l %%j in (1,1,80) do (  
set /a Down%%j-=2  
set "x=!Down%%j!"  
if !x! LSS 0 (  
set /a Arrow%%j=!random!%%3  
set /a Down%%j=!random!%%15+10  
)  
set "x=!Arrow%%j!"  
if "!x!" == "2" (  
set "line=!line!!random:~-1! "  
) else (set "line=!line! ")  
)  
set /p=!line!<nul  
)  
goto line
