text animation using frame change

Using the very basic concept of the frame_change event, it is possible to update the body of a text object and render it as an animation.

	import bpy
	from random import choice
	from string import ascii_lowercase as lowercase
	if not 'Text' in bpy.data.objects:
	bpy.ops.object.text_add()
	def make_char_list():
	text = "This is the Text and some hullabaloo"
	char_list = []
	for idx in range(len(text)):
	random_text = ""
	for token in range(idx):
	if text[token].isspace():
	token = text[token]
	else:
	token = choice(lowercase)
	random_text += token
	char_list.append(random_text)
	char_list.append(text)
	return char_list
	char_list = make_char_list()
	def my_handler(scene):
	frame = scene.frame_current
	if frame > len(char_list):
	current_string = char_list[-1]
	current_string = char_list[frame]
	bpy.data.objects['Text'].data.body = current_string
	bpy.app.handlers.frame_change_pre.append(my_handler)
