you need to find a volunteer to make the pattern have the two corner  blobs

\starttext

\startMPcode
     path p, q, r, b ;
     path p ; p  := unitsquare xyscaled (4cm,4cm) ;
     draw p ;
     draw p
         withpattern image (
             draw (llcorner unitsquare -- urcorner unitsquare) scaled 5mm ;
             % how to get the corner dots
         )
         withpatternscale 1/16
         withpen pencircle scaled 1mm
     ;
\stopMPcode

\stoptext
