draw shape along moving trajectory

I don't know what shape you want...I am taking a random shape here, it looks weird. But this is the procedure you have to follow:

clc; clear all ;
k = rand(10,2)/10 ;
k = [k ; k(1,:)] ;   % a random shape

% random trajectory
N = 10 ;
x = rand(N,1) ;
y = rand(N,1) ;
for i = 1:N
    plot(x,y,'.-b') ;
    hold on
    patch(x(i)+k(:,1),y(i)+k(:,2),'r')
    hold off
    pause(0.1)
end
