The puzzler is for you to understand why I only increment by 1/2 ;-)
Perhaps someone else can suggest a better solution?


numeric counter; counter := 1;

numeric u; u:=0.5cm;
save p; path p; p := fullcircle xyscaled (u,u) randomized 2pt;
pickup pencircle scaled 1pt;
fill p withcolor green;
draw p withcolor blue;
draw textext(decimal counter) withcolor red;
counter := counter + .5;
