By yours truly.
Pen lines doodled and scanned, then fixed up.
This variant was accomplished with the following hex color codes: #a52a2a #942525 #842121#731d1d #631919 #521515 #421010 #310c0c #210808 #100404 #000000 — and these scripts, all available from http://ift.tt/2cECtEr: potraceAllBMPs.sh, BWsvgRandomColorFill.sh, renumberFiles.sh [svg], allSVG2PNG.sh, ffmpegAnim.sh [7 29.97 20 png]. Tools used: A flatbed scanner, Photoshop, Adobe Illustrator (for svg node reduction while preserving virtually identical appearance), Inkscape, LibreOffice draw, Internet Explorer (for quick svg previews), cygwin (to enable all of the listed .sh scripts), ffmpeg (to create the video via ffmpegAnim.sh) and the SVGOMG web service (to optimize an svg and prepare it for use by BWsvgRandomColorFill.sh).
