MATLAB: What is your unusual use of MATLAB

beerdiscussionhumorMATLAB

I remember reading a blog (maybe by Doug Hull) that someone uses MATLAB to send emails and check local weather. I am just wondering what is your unusual use of MATLAB. Maybe there is something that might surprise every one.
In answering a question today, I found out that I can use MATLAB to listen to online music.
system('C:\WINDOWS\system32\dllcache\wmplayer http://www.satelitemusical.net/mj-akon-hold-my-hand.wma')
Of course not really have to use MATLAB, but, it's cool.
What is your usage?

My cat likes to chase the laser pointer. Once the battery has run out and I wrote a few lines of code to give him the entertainment :)
Something like that (Lissajous curve):
figure('menubar','none','color','k')
h = plot(sin(sqrt(2)*0+sqrt(3)),cos(sqrt(5)*0),'r.','MarkerSize',20);
xlim([-1 1])
ylim([-1 1])
axis off
for t=0.01:.01:100
    set(h,'xdata',sin(sqrt(2)*t+sqrt(3)),...
        'ydata',cos(sqrt(5)*t))
    drawnow
end
