System in Motion

 

Growing vs Building. The idea of growing inhabitats  instead of building them still belongs to sorcerer’s apprentices but computing can give us glimpses. This is a visualization of previous cell[f] assembly code (based on Conway’s Game of Life).

The animation is coded in processing with bespoke camera angles.

Processing source code below:

}

if ((Generation<MaxGeneration)&&(Generation>=0)) {
arrayCellTwister(arrPt, Generation);
