Timed changing message on screen

[Jeff]

you could use the following

#Stop and go message
text_go=vizinfo.add('GO')
text_go.translate(.5, .9)

def stopSign():

	text_go.message('STOP')
	vizact.ontimer2(1,0, text_go.message,'GO')

vizact.ontimer(10,stopSign)

your first example uses viz.waittime but its not in a director function
