is it possible when using metafun, given a path to rotate the pen

e.g. rotating the pen while drawing a line?

it probably is possible, yet how?
Any hints?
AFAIK it’s not possible to change the pen during the path.
At least that was true a few years ago.
Here's the logo of the CMS:
\startMPpage
path p ; p := fullcircle xyscaled (100,70) ;
path s ; s := nepstroke (1000) (.25 + uniformdeviate(5)) ;
path t ; t := nepstroke (100) .25sin(10*pi*strokestep/strokesteps) ;
picture c ; c := lmt_outline [text = "CMS", kind = "path" ] ;
c := c shifted -center c ;
fill p penstroked s withcolor darkblue ;
for i within c :
fill ((pathpart i) penstroked t) scaled 3
withpen pencircle scaled 3
withcolor darkred
;
endfor ;
\stopMPpage
This will keep you occupied for the rest of the day.
