This is one of those cellular automata programs set on an imaginary desert world populated by white and black daisies. The white daisies love the heat of the sun, but (being white) they tend to reflect sunlight and cool down. The black daisies love cool, but (being black) they tend to absorb more sunlight and heat up.
This program simulates the struggle between white daisies, black daisies and desert, producing some pretty patterns and eventually (if you're lucky) establishing a peaceful coexistence.
After compiling the program, try running it with the following options:
./daisy -b 0.2 -w 0.2 -s 256,256
If all your black daisies die out, restart the program. You can fiddle with the initial conditions (try ./daisy --help for instructions).
