I looked into my personal squeak archive.
Here is the game and the mail.

Folks -

Someone asked about this a year ago, and I sent out a file.  Check the mail
archives.

I don't know if this is what you want, but here's s port to Squeak of my BitBlt Life program that first appeared in the August 1981 isue of Byte magazine.

To run it, execute...
	    Display restoreAfter: [(Life new size: 400) run].
This will run noticeably faster if you set your display depth to 1.

It does a 400x400 generation in 43ms on my 250MHz G3.

Enjoy
