using friendly virtual agent to draw by itself
its a bit drunk so movement direction and speed is randomised
draws the name accoring to array "map"
in which "." is black and numbers 1-4 are colors

one can use variable SPEED to control how many steps agent moves
one can use variable FADEOUT to control how much past traces are fading out.
