Annoyingly I didn't make a note of where I found the algorithm and I can't find the source now, but I remember being struck by its simplicity and deciding I had to find a use for it.
The meat of it is:
z = (sum of surrounding cells) - z;
z -= z >> 5;
"In Europe, in contrast to Japan and the US, there are restrictions laid down by the EPC on how far computer programs may be patented. Programs considered to make a “technical contribution” – such as controlling a robot, or making the internal operation of a computer more efficient – can be patented; general application programs – such as word processing software – cannot."
...
"In this case, the Review believes the balance of evidence lies in continuing to withhold patent recognition of non-technical computer programs as part of a sustained effort to deal with the growing and dangerous problem of thickets. The UK should seek to convince its European partners of the force of this case.
Similar considerations apply to the patenting of business methods (for example, particular pricing and marketing schemes) which are also allowed in the US but not in Europe – and unlike in the computer program area, there is no sizeable European lobby arguing for their patenting. Here, the correct course is clear: Europe should continue to resist the patenting of business methods."
