In June of last year, we wondered about the flags that appeared on the exterior wall of 540 Laguna St., and in September we learned that the Laguna art wall had officially become an ongoing art project. Now, a husband-and-wife creative team is working on a new installation that could prove the most involved and eye-catching yet.

Natasha Lisitsa and Daniel Schultz of floral design shop Waterlily Pond are behind the new project.

"I am primarily a floral designer," Natasha told us, "and Daniel has an architectural background and is a furniture designer." Together, the pair collaborate on installations inspired by flowers and the organic world, and have had their work shown at the de Young, SFMOMA, and St. Mary's Cathedral (see some of their past work here).

Joe Theisen, the owner of the building at 540 Laguna, approached the pair after seeing some of their work, and asked if they would like to design an art installation for the building's exterior.

"We're really excited about the opportunity," said Natasha. "We've never done outdoor public art, and it's an interesting opportunity." Because it will be outdoors, she said, they got inspired by the idea of using the wind to make it a kinetic installation.

Plans include 22 teardrop-shaped sculptural units made out of aluminum, with tree branches installed inside each unit and brightly-colored fabric ribbon interwoven throughout. Each unit would be connected to a swiveling piece of hardware that would allow it to rotate with the wind. "We're hoping that it will be a beautiful moving sculptural art piece."

Natasha and Daniel are financing the project themselves, and have launched an Indiegogo campaign to cover the cost of materials and fabrication. So far, they've raised more than $1200 of their $3,000 goal, with a month left to raise the rest.

Here's a preliminary look at what they're planning:

Natasha and Daniel are longtime San Francisco residents and self-professed big fans of Hayes Valley, and they say they hope to create an exciting addition for the neighborhood. "Having people walk by and see it and be interested," Natasha said, is the goal.

Natasha says they are hoping to install the project before end of January, and are shooting to have it up for two months to start. "If the owner likes it and it looks good, we'll leave it for longer."
