Backtrack with ``q'' (or right mouse button) to the start of the program.
At the very first prompt enter ``s'' for forwards only.
Enter ``return'' until a ``wiring:...`` prompt window appears top right. Enter ``2'' (for regular 2d).
At the next prompt window enter ``return``.
The next prompt window sets the size of the 2d lattice. Accept the default size 36x36 (for a faster computer increase the size to say 50x50).
At the next prompt window enter 9 (the neighbourhood size).
At the ``Select n=9 rule,...'' in the main sequence of prompts, enter ``f'' for the ``game of life'' (the lookup-table of this rule will be displayed as a bit pattern..
Keep entering ``return'' to accept defaults for the seed etc.
At the OUTPUT PARAMETERS prompt enter ``s`` for ``space-time pattern only``.
Enter ``d'' to accept all space-time pattern defaults.
The 2d space-time pattern is generated in the top left of the screen. An ``interrupt key index'' on the right of the screen gives a list of key presses to change settings ``on the fly``.
Enter ``t'' to toggle between the 2d display and a 3d isometric projection. (imagine looking up at the ceiling of a transparent lift shaft). The ``game of life'' may soon settle to a stable or null state. To re-seed the network enter ``k'' for a new (random) central block. With luck gliders will emerge. Note that colours represent the cell's rule-table lookup rather than its value, making the 3d graphics clearer (key ``3'' toggles this colour setting). Other key pressed include changes to the rule, wiring, seed and scale.
Enter ``q'' to interrupt (and backtrack).
