Lifey is a simple drawing program that implements Conway's Game of Life, using a web browser. It utilizes the performance and convenience features of the modern web, with the familiar interface of industry-standard pixel editing software. It includes an extensive browsable library of historical patterns in JSON format. It supports touch interfaces, including multitouch fingerpainting and pinch-zooming. It supports pattern sharing via URL, with the ease and convenience of zero-install software.

Conway's Game of Life is probably the most programmed game in the history of computing.
