|Minecraft. Nikon D7000|
I remember well the hours I spent as a kid on my ZX Spectrum writing code and attempting to write games. There were a few early 3D offerings in the later years, but now Minecraft seems to be supplying the young engineers of the future with a world of their own to create in.
The laws of physics are a bit different in the Minecraft world; they have a definite whiff of 'God is a computer scientist' about them.
