Yesterday’s generative art piece, called “Circlecells” (these names are amazing, I know):
Detail:
The code is on GitHub. I also posted a few process pics to Twitter yesterday. There are also three other accompanying pieces in the set generated with different seeds: 02, 03, 04.
Explanation:
There’s a 20×20 grid which gets populated with an initial seed population of living/dead cells. (I get a random value between 0 and 5; if it’s 0 or 1, the cell is alive.)
The lines are drawn from any living cells to any immediately neighboring living cells.
The size of each circle is dependent on how many living neighbors the cell has.
The initial round is drawn in light tan, then the grid is run through a modified Conway’s Game of Life (any cells with 2, 3, or 5 living neighbors are alive in the next round).
Two more iterated rounds are drawn, one in a slightly darker tan and the last in dark red. (Drawing is done with the multiply blending mode.)
I textured the piece in Photoshop afterwards, using some Kyle T. Webster brushes — add canvas, add noise, encaustic grit, a couple others that I can’t remember.
