[math-fun] Hilbert function as images

I wrote up a little program to generate .xpm images of iterations of Hilbert where pixels are of this form: 32 01 Where 0-3 are either shades of gray or R,Y,G,B. 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 ...
