It would be really cool to make some slightly more usable programming language that compiles to Brainfuck so that mortals could write non-trivial programs in it and impress their friends.
It's not impressive, though. It's not surprising that someone is able to create a program using a Turing-complete language. It's just surprising that they decided to waste their time with an unreadable one. It's far more impressive to do basically anything else related to programming.
