@enkiv2 ban TTF
@enkiv2 like I know you're probably talking about Javascript in HTML or maybe Word macros, but Truetype also has a turing-complete hinting system, Postscript is a whole scripting language, Excel and PowerPoint have ways without macros or VB, apparently templates in MediaWiki qualify, and at some level instructions in your computer are translated to something opaque anyway… What I'm saying is, there's precedent.
This idea of "accidental Turing Completeness" reminds me of "Wang's Carpets", a short story by Greg Egan:

His fiction trades somewhat crappy characterisations (but to be fair, mostly of post-humans) for mind-blowing SF ideas.
The only online version I can find is probably illegal:

I always think of Greg Egan's fiction as:
"Here's this cool comp-sci/physics idea!"
"Neat, what does it imply?"
"... I dunno. But probably soul-crushing depression and paranoia."
"Ah yes, the two great forces of the universe."
