Dandelions are weeds on most North American lawns and we spend money, time and energy getting rid of them. But here’s a painting of dandelions by Jie Qi that you would most certainly want to hang on your wall. ‘Pu Gong Ying Tu’ (Dandelion Painting) is an interactive painting that responds to sound. Hidden behind the painting is a circuitry of microcontrollers, LEDs and microphones. In fact, each dandelion has a hidden microphone behind it that ‘listens for wind.’ When you blow on the white puffs, the seeds disperse and generate new yellow flowers. (The puffs and flowers are programmable LED lights.) These flowers begin as yellow dandelions, but after a few moments bloom into responsive white seed puffs.
