Python script to create a matrix on the linux terminal

Use the following script to create a matrix like background on the terminal.

	import sys, termios, atexit
	from select import select
	import curses as cur
	from curses import wrapper
	import time
	import datetime
	import random
	# save the terminal settings
	fd = sys.stdin.fileno()
	new_term = termios.tcgetattr(fd)
	old_term = termios.tcgetattr(fd)
	# new terminal setting unbuffered
	new_term[3] = (new_term[3] & ~termios.ICANON & ~termios.ECHO)
	# switch to normal terminal
	def set_normal_term():
	termios.tcsetattr(fd, termios.TCSAFLUSH, old_term)
	# switch to unbuffered terminal
	def set_curses_term():
	termios.tcsetattr(fd, termios.TCSAFLUSH, new_term)
	def putch(ch):
	sys.stdout.write(ch)
	def getch():
	return sys.stdin.read(1)
	def getche():
	ch = getch()
	putch(ch)
	return ch
	def kbhit():
	dr,dw,de = select([sys.stdin], [], [], 0)
	return dr
	if __name__ == '__main__':
	atexit.register(set_normal_term)
	set_curses_term()
	stdscr = cur.initscr()
	cur.start_color()
	cur.noecho()
	cur.cbreak()
	cur.curs_set(0)
	stdscr.keypad(True)
	cur.init_pair(1, cur.COLOR_GREEN, cur.COLOR_BLACK)
	x=datetime.datetime.now()
	cols=lines=0
	cols=(cur.COLS)
	lines=(cur.LINES)
	count=10
	x=random.choice([0,1])
	stdscr.nodelay(True)
	while 1:
	if kbhit():
	ch = getch()
	break
	for x in range(0,cols-1):
	for y in range(0,lines):
	data=random.choice([0,1])
	stdscr.addstr(y,x,str(data),cur.color_pair(1))
	stdscr.refresh()
	print("done")
	cur.nocbreak()
	stdscr.keypad(False)
	cur.echo()
	cur.curs_set(1)
	cur.endwin()
