Seattle-based artist Dan Corson created this awesome interactive, solar-powered art installation entitled Sonic Bloom. It was commissioned by the Pacific Science Center along with support from Seattle City Light’s Green Up Program. The installation is situated outside the Pacific Science Center, which is on the grounds of Seattle Center, the city’s park, arts, and entertainment center originally constructed for the 1962 World’s Fair.

Sonic Bloom consists of five giant, colourful, solar-powered flowers which absorb the sun’s energy during the day and are illuminated by it at night via patterned LED lighting.

"Sensors located in each flower are triggered by people’s movement, as the 40’ high by 20’ wide super-sized flowers set off a chorus of interactive harmonic tones. Each flower has its own distinctive set of notes, simulating a singing chorus. Engaging the public it is possible to compose and conduct music together, or just by walking through to randomly set off a harmonic sequence. the interactive choral sound component works both day and night providing a dynamic and ever-changing sonic landscape."

The top of each flower has also been mounted with 46 locally-made photovoltaic cells that collect solar energy which is then fed back into the city’s electrical grid. “This sustainable feature completely offsets the energy-efficient LED lighting and speaker electrical consumption for the project.”
