Today marks the release of the first playable beta of CorsixTH, an open source Theme Hospital clone which I started a few months ago.

It's been a while since since my first blog post on Theme Hospital, and there has been a reasonable amount of development since then, so I thought I'd post a video showing some of the new stuff:

As before, if you're interested in grabbing a copy, or contributing, then see the Google Code project.

Observe my wonderful Lua ASCII art creation:

As an improvement on my prior post, this valid Lua program has a more interesting whitespace arrangement, has less string literals, and less alphanumeric characters (no "byte" in this code, whereas the previous post does).

As a continuation of my Lua abomination series, the below code is surely one of the most indecipherable versions of print 'Hello World' that you're likely to see.

_={_=_G}for--[[]]__--[[]]in(next),_["_"]do(_)[_]=(__)_[#_[_]],_[_[_]:byte(-#"#"

(If you don't believe me, it does print Hello World).

The aim was to use as few alphanumeric characters as possible, and I think I did fairly well - you've only got "G", "for", "in", "next", "do", "byte", "end", and "sub". For a language which typically is full of alphanumeric characters, I consider it quite impressive. As an added bonus, there is also no whitespace.

Only about half a line of the code is an encoding of "print'Hello World'" - the other lines just perform generic decoding. That's right; not only this is an obscene obfuscation, it's also an easily reusable obfuscation.

I thought this wonderful little wordplay from the Lua mailing list deserved some more visiblity:

Person A: IMO python is by far the better language for "first programming language" than Lua.
Person B: If you're going to make an audacious assertion, please back it up with justification :)
Person C: Justification changes the syntax.

Unfortunately, you need to have a fair bit of knowledge on computer programming languages to appreciate it.
