The new banner is Conway’s Game Of Life. To quote Wikipedia:
The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970
This version is in a small playing space for speed, and is lightly mouse interactive (try moving the mouse over the banner).
I started with an example found by Google, which I then adjusted for visual style, speed, and to add the interactivity.
