Just looks like an upside-down little boy, right? Well, if you rotate the 53-bits of the double precision fraction component so that each becomes the highest valued bit, you can easily see the hidden images:
NOTE:bitrotate is a version of the built-inbitshift that I wrote to perform a circular shift of the bit pattern instead of discarding bits that overflow. I'll be placingbitrotate on the FEX soon, but for now you can just replace it withbitshift in the above code.
The spy function without arguments makes a cool figure (my current avatar).
The why function says random things.
Matlab comes with a great sound clip for those moments when you find a solution for a huge problem
The pie function (matlab 2008b and maybe later versions) doesn't allow to place the labels in a specific place but in the function code there's a variable that allows the text to be inside the pie and you might also set the distance from the center of the pie, here's a little hack that I did to pie
From the Control System Toolbox work without any arguments, there's a sort of demo that they make, very nice, I was using them for years without noticing, nice surprise, wonder why the tf function doesn't also have the same behaviour
Onhttp://www.walkingrandomly.com/?p=2949, Cleve says "As our code base has increased, including such goodies in the MATLAB core has become problematic because of the strain it puts on rigorous automated testing. It is still possible to include them in a few “leaf” M functions, like “spy”, that other functions do not depend upon." so they will probably be fewer as time goes on.
