a=.5;
b=[12 15 12 5];
c=[7 0 -7 -10];
hold on
axis equal
fill([0 0 50 50],[12 -25 -25 12],'r')
fill(x,y,'y')
for i=1:4
    fill(a*x+b(i),a*y+c(i),'y')
end
axis off
f=getframe(gcf);
figure
f=f.cdata;
[x,y]=meshgrid(1:size(f,2),1:size(f,1));
surf(x,y,25*sin((x*2+y)*.015),f,'edgec','n');
% camlight headlight;
axis equal off;
set(gcf,'color','w');
