I just submit this for you, Lembik, to have a complete list.

v=-100:100;
[y,x,m]=ndgrid(v,v,0);
n=75;
while 1;
    pause(1);
    c=m;
    c(x+i*y==round(n))=1;
    imshow(c);
    colormap([1,1,1;.5,0,.5]);
    n=n*exp(pi*i/30);
end

Old version:

v=-100:100;
[x,y,m]=ndgrid(v,v,0);
while 1;
c=m;
c(x+i*y==round(75*(-1)^(s/30)))=1;
imshow(c);
colormap([1,1,1;.5,0,.5]);
s=mod(s-1,60);
pause(1);
end
