Import@f~StringSplit~"\n\n"~ListAnimate~1


Expects the file name to be stored in variable f.

This is the first time Mathematica's precedence rules for @ and .~.~. are exactly the way I need them.

Btw, this snippet could go horribly wrong if the file extension is anything else than .txt (because Mathematica will try to guess how to do the import based on that), but luckily that file ending is part of the challenge specification.
