Well, I was working on some software to do panoramic image stitching over the weekend. Several hours of work yielded some phase correlation code that seems to work well about 50% of the time, and fail tragically 50% of the time. My brain wasn't up to the task of further analysis, so I decided to waste some time making an mpeg or two of the Mandelbrot set. I modified an old .signature program I had to dump a whole bunch of pgm files, and then used a program I call ppmtocmap to extract interesting colormaps from photographs to color them. A few more command line utilities, and voila, an MPEG1 and MPEG2 zoom into the Mandelbrot set.
