Pu Gong Ying Tu is an interactive painting of a dandelion field. When you blow on the white puffs, the seeds disperse and generate new flowers. These flowers begin as yellow dandelions, but after a few moments bloom into responsive white seed puffs.
Beneath the painting is the circuitry– made up of microcontrollers, LEDs and microphones. At each dandelion, a microphone listens for wind. Yellow and white LED lights, which can be coded to brighten or dim, act as dynamic programmable paint strokes which make up the petals and seeds.
The piece is part of a series called Programmable Paintings, which blend traditional elements of painting–such as color, texture, composition–with the intelligence and interactivity of electronics and computation.
This work was made in collaboration with John Clifford, with guidance from Brian Chan.
This painting is inspired by Jessie Thompson and Zachory Berta’s:
