The phenomenally successful game Minecraft is unique in that it allows players to build things in much the same way that they are built in real life — brick by brick. Among its tons of projects, people have built the entire world of Star Wars, a replica of Manhattan and several art works. Using the in-game material “redstone,” players can even create functioning circuits. Apparently, hardcore gamers have been building upon this to create virtual hard drives, which are actually programmable.
This is a gif demonstrating the individual building blocks of a Minecraft hard drive. Hundreds or thousands of these are necessary to create more complicated systems.
The idea of a computer-within-a-computer is pretty fascinating, and dedicated gamers still plugging away in the game could create even more advanced technology in the near future.
