Hi, Hans,
In your "metapost graphics" pdf document, I can find a card which
randomizes points in a path of Christmas tree, how to do that? thanks.

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'
