Amazing art was created with just what your standart ANSI Terminal was offering you.
My best computer right now, the KIM-1 clone PAL-1 is connected via the serial line to this hexacore loser PC, working as a slave for the 1 MHz machine. Tera Term, the state of the art terminal program understands ESC commands, a sequence of charaters beginning with ASCII 27 (ESC) and '[' to manipulate things like color, lines, and moch much more.
You can use this in KIM-1's microsoft BASIC to give your games a bit of color, or even make action games with manipulating the cursors position.
Here is a short library thatshows you how to use it kb9_ESC_LIB
Have a nice evening,
