Minecraft, it has blocks.
Download for fullview, deviantart's resize algorythm raped the image as usual.
EDIT: fiddled around with the text, should be less ugly. I hope.
EDIT 2: IMPORTANT: On permission for usage of the image.
People are free to use this image on personal stuff such as backgrounds for their desktop, cell phone, or whatever.
Equally you are free to use this image on youtube videos and other forms of dynamic media, given that a link to this page is provided in the video description.
However, this image is to not be used as personal user images, avatars or whatever situation one's identity would be associated with it. Equally it should not be used as background or logo of a website, nor of downloadable packs and such (I found it recently as the logo of a piratebay torrent a friend linked me, although complaining about copyright there feels a little... useless?
If you are not sure what category your usage of the image falls in, or have any questions, my inbox is open for questions.
EDIT 3: A DD, wow! I'm so happy. Thanks everyone
