Channel IDs of empty (i.e., dead) tiles are color-coded red. Live cells with identical Channel IDs are color-coded with identical (but arbitrary) grayscale values.

Signals data is double buffered. Signals 1 and Signals 2 correspond to Level 1 signaling while Signals 3 and Signals 4 correspond to Level 2 signaling. Playing from just one buffer will render signal patterns at just odd or just even updates. To view consecutive updates, alternate stepping a pair of buffers.
