16-year-old Makes Working Scientific Calculator in Minecraft

http://www.tomshardware.com/news/Minecraft-Calculator-Graphing-MaxSGB-Scientific,15109.html

16-year-old “MaxSGB” has created a working scientific/graphic calculator inside Minecraft. On a virtual scale, the functional device is enormous — enough so that anyone in the real world would become a red blot of meat and bone staining the road if they fell from the very top. Honestly, his virtual machine looks more like a giant cargo ship ripped from a sci-fi movie than a working calculator. Yet type your problem out on the keypad, and the answer appears on a large white display mounted on the side of the monstrous brick structure. No spaceship can do that… can it?

The nxcEditor can be used to program a NXT robot with a Linux operating system (the NXC source code is highlighted). The program can optionally be run on the real robot or the nxcSimulator, which is integrated in the nxcEditor (the official NBC compiler is invoked from the nxcEditor). The nxcEditor (as well as the nxcSimulator) is designed for teaching programming to beginners.
