He Writes a Programming Language with Minecraft Blocks

Screenshot from the YouTube channel SethBling

This guy basically just recreated a BASIC interpreter in Minecraft.

In the video, the YouTubeur explains that he has a degree in computer science, but still impressive, and gibberish to a lot of people haha...

With this you can compute programs from basic math operations to more complex stuff like listing the prime numbers, but it seems like it takes a lot of time for the system to process this.

Two whole weeks were required, he tells, to build the whole thing.
