Here is an example. You will have to randomize the rotation and
translation as well as the characters.
convert -size 290x70 xc:white -bordercolor black -border 5 \
-fill black -stroke black -strokewidth 1 -font TimesNewRoman
-pointsize 48 \
-draw "rotate 30 translate 40,30 text 0,0 'A'" \
-draw "rotate -10 translate 65,50 text 0,0 'n'" \
-draw "rotate 5 translate 110,40 text 0,0 '3'" \
-draw "rotate -20 translate 130,100 text 0,0 'c'" \
-draw "rotate -5 translate 190,70 text 0,0 'x'" \
-draw "rotate 10 translate 240,10 text 0,0 'H'" \
-fill none \
-strokewidth 2 -draw "bezier 20,70 45,10 100,70 140,10 " \
-strokewidth 3 -draw "polyline 150,20 200,60 280,30 " \
