An implementation of Conway's Game of Life which is displayed according to a generalisation of the smoothing algorithm used by the Mullard SAA5050 (BBC "MODE 7").

The smoothing is derived from Ben Harris' Bedstead font generator. The idea of applying this to Life is the fault of Simon Tatham.

This is implemented as a rule file for Golly, since that can include both custom rules and custom icons for cell states in a rules file. Since it uses the new rule format, it requires at least Golly 2.5; it would however be fairly easy to produce a version that worked with older Golly.

To play with it, you just need Bedbugs.rule -- almost everything else is machinery for generating that. Detailed instructions are at the top of the file.
