'\b' is a backspace, so.....

import sys,time

chars = ['|', '\\', '-', '/']
out = sys.stdout

def raw_print(txt):
    out.write("\b" + txt)
    out.flush()

while 1:
    for x in range(len(chars)):
        raw_print(chars[x])
        time.sleep(0.5)


Save as a script and run it from your command prompt.
