It might be interesting if the pixels were computed additively, picking up some color rotation or darkness at each level of iteration. We might see a path that traced out the square, while going from white to black or red to blue.

Sources, binaries and PNG images here, with both images in their original (mostly tiny) sizes and scaled to a uniform 2048x2048 size: http://lunkwill.org/src/hilbert/ So, for instance, you might go here: http://lunkwill.org/src/hilbert/color/ Then look at these: http://lunkwill.org/src/hilbert/color/scaled-1.xpm.png http://lunkwill.org/src/hilbert/color/scaled-2.xpm.png ... _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
