Conway's Game of Life is one of the first computer games. It is a mathematical 'game' in which you create patterns in a grid and according to the following rules, you can watch the pattern evolve.
You can play an on-line version here if you can be arsed to faff around with java settings.
"But how would those rules work with the De Stijl paintings of Piet Mondrian", I hear no one ask. Well, that's what I've created below.
Just roll your mouse over a painting for it to play out, and click the painting to reset it to its original form.
