Here are various implementations of Conway's Game of Life.
This was a private project, which I created just for fun. That's why I didn't bother to make it work in Internet Explorer ;)
The first test was made using DIVs. It get's pretty slow, when you resize the field.

Another test implementation was with SVG.
The graphic only contains the code to draw the cells and change the cells with
the mouse (just click and drag), but no code to calculate the next iteration.

A third implementation was with the Canvas tag of the HTML5 Working draft.
It is much faster than just using DIVs.
