What I should have said is that Zachtronics has the market cornered on programming puzzle games for programmers. I could suggest Human Resource Machine to someone who has never programmed before, but I would never do that with TIS-100.
Making a TIS emulator in Elixir sounds like a fun and useless project.
And according to Zach, the intended market wasn't just programmers (which is why he explicitly killed bit manipulation, and the largest number a TIS-100 register can hold isn't a power of two), and I've heard tales of non-programmers enjoying it.
Then again, if you like Zachtronics games, especially TIS-100, then have I got a hobby for you...
