These are pictures taken to demonstrate minimal living shapes in the corner, on the edge, and in the middle of the board.
- The circled coins represent eyes. I.e. by being there, they are proving that there is space for an eye. I've use 'heads' for these 'eyes' and 'tails' (an Echidna, on our national 5 cent piece) for actual stones (all the same colour).
- The lines between the centres of coins mean the coins are touching and hence connected.
- Notice that no pieces need to touch the 'eye' stones (which I call 'ghost stones').
