The 14th page is an illustration of the circulatory system. It’s done as a doodle that is inspired by the disassembled cassette player from Doodle 12 of 100. In both pieces the insides are laid out like an Ikea illustration. The systems as a still images makes my brain happy. The use of a fountain ink brush adds a lot of playful character to both pieces. More ‘system doodles’ exploration will happen. Keep watching the 100 day sketchbook project. I would love to hear from you, What system would you like me to doodle in the pink sketchbook?
