This year Mojang released a bundle of screensavers for 64-bit Windows 7 and higher.
It is called Minecraft Plus and can be downloaded from this page.
There are multiple hidden messages in the mark-up of the download page, here they are:

I definitely wasn't hired for my webdev skills haha  
What is this? Where are all the libraries? This is never going to work in IE  
Is that written by hand? Puzzling!  

After downloading the compressed archive, I was greeted with MinecraftPlus.scr, an executable with a glowing squid for its icon that displays a random Minecraft-themed screensaver.

The program will display a randomly selected text message,
here are all the possible messages:
Busy config window|Sorry, I don't have time to handle this right now
Optimistic config window|Nothing here, but I'm sure something will eventually show up
