This week Formafantasma unveiled experimental lighting designs at Milan design week and Cerith Wyn Evans illuminated the Tate Britain with neon scribbles. Both feature in this week's Pinterest roundup of popular lighting installations.
Amsterdam-based design duo Formafantasma presented a series of lighting designs and experiments in Milan this week, including golden hoops that project circles of light and slender beams that create colourful refractions.
Also this week, Welsh artist Cerith Wyn Evans suspended almost two kilometres of neon lighting shaped into sharp lines and sweeping forms in the Tate Britain's Duveen Galleries.
A giant cloud of balloons was installed under the roof of the 19th-century Market Building in London's Covent Garden by French artist Charles Pétillon. A gently pulsating white light, designed to mimic a heartbeat, illuminated the structure from within.
Illuminated glass droplets full of bubbles appeared to fall from the ceiling of a Tokyo gallery in Torafu Architects' Water Balloon installation. Each of the 36 hand-blown bulbs pulsated with light in the dark space.
Architects Marion Moustey and Alexandre Arcens strung an undulating canopy of lights between two docks to create Sensual Wave. The 160 spherical lace-wrapped lights were reflected in the water at night, when sensors automatically illuminated the installation.
Canadian firms Lateral Office and CS Design placed 30 glowing seesaws in a Montreal public square to create the Impulse installation. In-built LEDs and speakers caused the light intensity and sound to change as each seesaw moved up and down.
Japanese architect Sou Fujimoto used spotlights, mirrors and specially composed sounds to create a "shifting forest of light" for fashion brand COS at last year's Milan design week. Cone-shaped beams pierced through the pitch-black room, fading on and off in response to visitors' movements.
For last year's London Design Festival, British designer Lee Broom transformed his east London store into an experimental installation inspired by the 1960s Op Art movement. Wall-to-wall infinity mirrors reflected each of Broom's striped Optical pendant lamps.
A billowing woven sculpture by American artist Janet Echelman was suspended above London's busy Oxford Circus junction. At night, the piece was illuminated with coloured projections that were determined by nearby smartphone users who chose to participate.
Canadian lighting brand Bocci filled the rooms of its Berlin headquarters with room-sized installations, including a tree-shaped sculpture with lights held on the end of branches, and a cloud of globular lights.
