At the time of this video, I'm taking a class at UC Berkeley called CS61CL, which is about machine structures. We are using Logisim (http://ozark.hendrix.edu/~burch/logisim /index.html) to make virtual digital circuits out of very basic elements such as logic gates, multiplexers, flip-flops, etc. Soon, I decided to give myself the challenge of recreating Conway's Game of Life using Logisim.
The hardest part was overcoming the problem of getting the states of all 8 cells around one cell when its directly connected to only 4. I achieved this by having the inputs to each cell have 2 bits, one for the cell directly next to the cell in question, and the other for the cell in the clockwise direction. Due to this handling of cells (especially in the diagonal directions), I needed to carefully route the wires such that when the circuits are put together in a grid, the inputs and outputs would match up and correspond to their intended behavior. This took about an hour of analysis, brain drainage, and trial-and-error.
