Damn, a customer. One of my final school projects in '91 was a text drawing program. Using it, I was amazed what effects I could get with text, background and foreground colours. Amongst other things it had line drawing, box fill with fg or bg colour.
Actually we made use of extended ASCII for our UI at the time ... you know, the solid bar/solid double bar, etc. So this isn't quite where we could have used it, but it's pretty close!
