New blog post: using complex numbers to draw spiral tilings. It's an old idea, but I've always wanted to explain it in full. Plus, this time I include an interactive tool for drawing your own tilings!http://isohedral.ca/escher-like-spiral-tilings/ …

One way of looking at it is as *potential flow* of an ideal fluid, adding together sources, sinks and vortices as functions of complex numbers. http://mathfaculty.fullerton.edu/mathews/c2003/SourceSinkMod.html … A very nice book that covers this is 'Visual Complex Analysis' by Tristan Needham
