Object: Create some beautiful and interesting growth patterns.

Hit RUN and see what happens.

You start with a few seeds on the main playing board.
Hit the GO button to create one generation of growth.
Hit the GO10 button to create ten generations of growth.
Hit the RUN button to create many generations of growth (until no new position painted).
Hit the CLEAR button to erase the board.
Hit the SEED button to place a random seed.
Click the seed number to change the type of seed dropped by the SEED button: 1= single seed, 2,3 = domino, 4,5,6,7 = bar-trimono, 8 = L-trimono, 9 = square(2x2)
Hit the board to place a seed (select a color from the color bar first).
Hit the LINE button (and then the from- and to-position) to draw a line.
Hit the COL-CYCLE button to cycle the colour used after every generation.
Hit the one of the buttons 1 to 7 to set the rotational speed in multiples of 45 degrees. Note that this setting influences the ROTATE button, the AUTO ROT button and the RANDOM button.
Hit the ROTATE button to rotate the 5x5 growth pattern (default: rotate by 45 degrees = 1/8 of a full turn).
Hit the AUTO ROT button to automatically rotate the pattern after every generation.
Hit the RND button to randomly rotate the pattern after every generation.
The types of allowed random rotations can be controlled by the brown button next to the RND button.

The two 5x5 growth patterns (A and B) determine the growth strategy set by you:
Pattern A is checked for all places on the main board, row by row, starting from the lower left corner.
There must be at least one black marker for growth to occur.
Black markers in the 5x5 pattern symbolise existing spots on the main board (of any colour).
Red markers symbolize positions that must to be empty for the growth process to happen.
Pattern B:
Green markers represent new growth. (Growth will only occur on empty board positions; no overwriting.)
Red markers cause the corresponding cells to die.
To change A or B simply click any position in the 5x5 pattern areas.
The markers in A will cycle through black, red and invisible.
The markers in B will cycle through green, red and invisible.

Please note that the colours used in the 5x5 pattern area have nothing to do with the colours used on the main board!

There are several alternative piece sets available.
These include a board with a grid.

There are a few sample games stored in the solutions folder.

Be patient; the game takes a while to load!

I have never seen anything like that published anywhere.
The resulting patterns are quite different and usually have smoother transitions and much rounder curves than those created with variations on the 'Game Of Life' or fractals. This can be useful for wallpaper or carpet desin. Hence this topic may be worth exploring some more.
