I honestly don't see how a Python or Ruby version would be much better than a shell version for this. Perhaps you can show by example?

I still contend that Ruby and Python are far more accessible than shell scripting, because they are very popular, especially Python, cross-platform, and less arcane.

    import os
    import random
    import sys
    
    os.system("clear")
    print "Hello there. I'm a computer. What's your name?"
    G = raw_input()
    print "Hello " + G + ". You are welcome to computer land."
  
    while True:
        print ""
        print "What would you like to do today?"
        print "1) Say something random"
        print "2) Make a maze"
        print "3) Exit"
        print "Enter your selection"
        S = raw_input()
        if S == "1":
            F = open("/usr/share/dict/words").readlines()
            W = random.choice(F)
            os.system("say {}".format(W))
        elif S == "2":
            for i in range(1, 3000):
                if random.random()>0.5:
                    sys.stdout.write("/")
                else: 
                    sys.stdout.write("\\")
        elif S == "3":
            print "Bye."
            exit()
        else:
            print "Try again."

My main gripe with Windows NT was that it would go back to the NT screen saver -- I couldn't get it to stay displaying my program, because there wasn't any true DOS mode.
