[GreenKeys] ascii art generation

[tony.podrasky]

Hello Simon;

RTTY art was done long before personal computers came into existence, 
and all that fancy stuff like lookuptables etc.

They were made by trial-and-error.

Don, WA6PIR, was amazing at RTTY art.

What he would do is either make a drawing on Teletype paper, or in
the case of his playboy centerfolds, put the picture in the Teletype,
cover it with plastic wrap (to keep the original clean), and do some 
practice runs. Once he got the basic picture down, he'd print it on
paper and punch tape at the same. Then he'd work on the shading. After
a while he knew what character combinations were needed for shading.

Very simple tools, but his picture came out great!

UE,
W6ESE - TONY
NNNN
