Hey Ashley
Found this via the reddit megathread - nice write-up.
As you asked, here's what I did with Ruby:

The real hero here is the `reduce` method, allowing the main code to work with groups of two and three interchangeably.
Also, `each_slice` makes it very easy to split the input into compartments.
I also write my solutions as executable Ruby files and I run them by piping the puzzle input via STDIN, as per Unix design principles.
I like the solution overall because it's in more of a functional style than imperative.
