Advent of Code

As a warmup for this year's Advent of Code, I'm re-reading and posting my solutions to last year's challenges. You can read, run and edit today's solution by following the post link.

Today's challenge had us building a simple Tetris clone with the additional twist that a regular sequence of jets of air blow the falling pieces sideways. Part two asked us to model this for a bazillion cycles, so we needed to keep an eye on the pattern of landed blocks and look for the same pattern to repeat.
