Life: Nothing + Nothing = Glider (WIP)

game-of-life code-challenge

In Conway's Game of Life, there is an infinite square grid of cells, each of which is alive or dead. The pattern changes each "generation". A dead cell with exactly 3 live neighbors (orthogonal or diagonal) becomes a live cell. A live cell only lives to the next generation if it has 2 or 3 live neighbors. These simple rules lead to very complex behaviors. The most well-known pattern is the glider, a pattern that moves diagonally one cell every 4 generations and looks like this:

The Challenge

Your task is to create two patterns which will eventually result in an empty board when by themselves, but when combined in a certain non-overlapping arrangement, eventually spawn a single glider and nothing else.

Rules and Scoring

• Each of the lone patterns must fit within a 100x100 cell box and may not contain more than 100 live cells.
• The combined pattern must fit within a 250x250 cell box
• The combined pattern is considered non-overlapping if and only if the sub-patterns' bounding boxes do not overlap.
• Your score is the sum of the number of generations it takes to get to the goal state for each of the 3 initial patterns. Highest score wins.
