I downloaded this file (listed on the Google Docs page as the .gz file, no choice available) and what I find in my download folder (on my recent iMac) is a file with an .mc extension, which my computer claims not to know how to open. (Nor do I.)
Any suggestions? Thanks,
It's a Golly pattern file in macrocell format. Get Golly here: http://sourceforge.net/projects/golly/files/golly/golly-2.4/ Unzip "mandelbrot3.gz" and call the result "mandelbrot3.mc". Drag this file onto Golly. It will take 10 to 20 seconds to open. It is a monochrome image of the Mandelbrot set, about 260,000 pixels wide and 220,000 pixels high. Click the mouse in the image to zoom in 2x. Shift-click to zoom out 2x. Use the "View > Fit Pattern" command (command-F or alt-F) if you get lost. If you're really patient, hit the spacebar (or tab or Return or command-R or...), and it will try to perform Conway's Game of Life on the pattern... all 10 billion cells. I think this is meant more as a proof of concept of the ability of macrocell compression, rather than a useful way to do the Mandelbrot set. I'm super-hyper-patient and have an 8-core workstation with 26 GB of memory. I am trying to switch the algorithm to HashLife... we'll see if that works.

As a computational tour-de-force, I decided to draw a large image of the Mandelbrot set and save it as a macrocell file. The iteration limit was 1000 iterations per pixel, and the bounding box is 258687 by 221688.
