# Living Culler

When you replace a square with four smaller squares, each a quarter the size of the original, the smaller squares occupy the same area, because 4 * ¼ = 1. If you discard one sub-square, then divide each of the three remaining sub-squares into four sub-sub-square, discard one sub-sub-quare and repeat, you create fractals like those I looked at in Squaring and Paring. The fractals stay within a fixed boundary. # ⇓ Square replaced with four smaller squares, each ¼th the size of the original Animated fractal Static fractal

This time I want to look at a slightly different process. Replace a square with nine smaller squares each a quarter the size of the original. Now the sub-squares occupy a larger area than the original, because 9 * ¼ = 2¼. If you discard — or cull — sub-squares and repeat, the resultant fractal grows beyond the original boundary. Indeed, sub-squares start to overlap, so you can use colours to represent how often a particular pixel has been covered with a square. Here is an example of this process in action: # ⇓ Square replaced with nine smaller squares, each ¼th the size of the original Animated fractal Static fractal #1 Static fractal #2

Here are the individual stages of a more complex fractal that uses the second process: Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 Stage 7 Stage 8 Stage 9 (compare Fingering the Frigit and Performativizing the Polygonic) Stage 10 Animated version Static version #1 Static version #2

And here are some more of the fractals you can create in a similar way:    Static version #1 Static version #2  Static version #2 Static version #2 Static version #3       Various fractals in an animated gif
