You could try to make something with this example code. \setupcolors[state=start] \starttext \startMPpage[offset=1cm] for i=1 upto 5000: v := uniformdeviate(100) + 1 ; h := uniformdeviate(v) / 5 * normaldeviate ; l := uniformdeviate(5) ; draw ((-l,0)--(l,0)) rotated uniformdeviate(180) shifted (h,-v) withcolor transparent(1,.5,green) ; endfor \stopMPpage \stoptext Wolfgang
