Pure Lua 5.2 Script (May work in 5.1, untested)

[Qwertygiy]

Also, looking at code will help new/intermediate scripters/programmers understand the concepts and syntax of the language.

That may be so, but that code is a heckuva lot more complicated than any I've ever used or seen used in Buildism, even by the creator. I may have seen some code that was that advanced in a few Roblox scripts, but we'd be talking 5,000 lines made by the finest, and definitely not the kind of thing your average builder would be using.
