In programmer Will Gallia’s Space Filling Portraits, complex mathematics become minimalistic portraits that even the most left-brained of us can enjoy. Using a Roland DXY 980 pen plotter custom-programmed with OpenFrameworks, Gallia depicts five mathematicians' portraits out of the space-filling curves they invented. In simple colors on plain white paper, the programmer “takes a raster image, posterizes it using K-means [clustering, a signal processing technique], then plots the path of a space-filling curve in different pens for the shades.”
Gallia’s illustrations honor mathematical theorists David Hilbert, Claude Shannon, John Von Neumann, Bill Gosper, and, in a tri-colored tribute, Giuseppe Peano, the father of space-filling curves.
Watch as Gallia and his Roland fill in the beards and bushy eyebrows of these famous math minds, below:
