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

just use 'uniformdevisate' or metafun operators like 'ramdomized' ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
