Mm, I wrote it.

It's in Python and uses the curses module. It doesn't check the terminal
size, so make it big enough and set font to tiny.

Source code follows:

#!/usr/bin/python

import time, curses, sys

def show(screen, filename, pause):
    f = file(filename)
    done = 0
    while not done:
        # read the current frame
        row = 0
        while 1:
            line = f.readline().rstrip()
            if line == '': #EOF
                done = 1
                break
            if line == ',':
                break
            screen.addstr(row,0,line)
            row += 1
        #display the frame
        screen.refresh()
        #pause
        time.sleep(pause)

if len(sys.argv) not in (2,3):
    print "Usage: %s <filename> [pause in milliseconds]" % sys.argv[0]
    raise SystemExit
    
filename = sys.argv[1]
if len(sys.argv) == 3:
    pause = 1.0 / sys.argv[2]
else:
    pause = 0.042
screen = curses.initscr()
try:
    show(screen, filename, pause)
except KeyboardInterrupt:
    pass
curses.endwin()
