Little script I wrote to make a mock matrix in command line

enter_the_matrix.py

# Enter The Matrix

import os, time, msvcrt, random

os.system('color 07')
os.system('cls')

x = [1,  2,  3,  4,  5,  6,  8,
    15, 20, 21, 32, 32, 32, 32,
    32, 33, 35, 36, 37, 38, 48,
    48, 48, 49, 49, 49, 63, 64]

while True:
	i = raw_input('Are you ready to enter the matrix? (Y or N): ').lower()
	if i == 'y':
		os.system('color 02')
		while True:
			try:
				for c in xrange(50):
					print '%c'% random.choice(x),
				time.sleep(0.075)
				if msvcrt.kbhit() and ord(msvcrt.getch()):
					os.system('color 07')
					os.system('cls')
					print 'Goodbye Neo'
					time.sleep(1)
					raise SystemExit
			except KeyboardInterrupt:
				os.system('color 07')
				os.system('cls')
				print 'Goodbye Neo'
				time.sleep(1)
				raise SystemExit
	elif i == 'n':
		os.system('cls')
		print 'Come back when you are ready'
		time.sleep(1)
		raise SystemExit
