- Shiva is a light-hearted varient of John Conway's Game of Life. It is,
- in fact, a screw-up I chanced upon when I was trying to figure out how
- to implement Life with the blitter. In effect, it is a superset of the
- ordinary Life rules, with the consequence that configurations tend to
- spread instead of dampening out.
-
- Nonetheless, it is close enough to ordinary Life that familiar structures
- (e.g., gliders) behave as expected. To provide some extra pizzazz, I
- rotate the solution bit-plane through all five bit-planes of the screen,
- creating a colorful and ever-changing display.
-
- For a particularly interesting effect, try the pattern:
-
- ooo
- o o
- ooo .
-
- This simple seed will grow into a complex and ever-changing universe
- with four points of symmetry (a consequence of the toroidal structure of
- the wrap-around screen). With the higher resolutions (i.e., with the
- smaller cells) it seems to go on forever.
-
- At the heart of the program is (implicitly) a nine-blit-per-generation
- solution to the Game of Life that I intend to release separately, in
- conjunction with an article on the blitter.
-
- I wish to express special thanks to Scott Everndon and Alonzo Gariepy
- for showing the way, and Tomas Rokicki for publishing a ten-blit
- solution.
