reusing a picture is more efficient
\startMPpage
draw fullcircle scaled (.06TextWidth - .05LineHeight);
picture t ; t := textext("\cldcontext{utf.char(0xEB09)}") ;
for m=1 step 2 until 10 :
path s ; s := (dir30--dir150--dir315--dir90--dir225--cycle)
scaled m;
n := (m * 50) ;
o := (m / 5) ;
for i=0 upto n :
draw t scaled (o * .025) shifted point (i/n*length s) of s ;
endfor
endfor
\stopMPpage
