Last year, the city of Austin’s Art in Public Places Program took a step forward when it initiated "Tempo," a series of temporary art projects in public parks.

The city commissioned a total of 11 "Tempo" pieces, all modestly scaled and in urban parks often overlooked by new civic developments, that offer fresh visual surprises to the cityscape.

As the 2013-2014 "Tempo" season will wind down over the summer, catch them before they’re gone. In fall, a new set of commissions will be unveiled.

"Treevolution" by Amy Scofield

South Austin Park, 1100 Cumberland Road; on view through Sunday.

Repurposed orange construction fencing and bright blue PVC pipes form a group of large-scale, very artificial-looking trees meant as a reminder that without care toward the preservation of our resources, we may doom ourselves to a future of fake nature.

"Dazzle House" by Lindsay Palmer

Boggy Creek Greenbelt, 1114 Nile St.; through June 1.

Lindsay Palmer used a "dazzle pattern" of black and white camouflage to paint her five simplified small scale house forms. Representing silhouettes of homes from the 1940s and 1950s — like those that surround East Austin’s Boggy Creek Greenbelt — the "Dazzle" houses are symbolically camouflaged as if to protect themselves from urban development.

"GloWave," by Melissa Borrell

Little Stacy Park, 1400 Alameda Drive; through June 8.

Solar-powered LED lights glow at night to illuminate Melissa Borrell’s playful sculpture, made of lightweight plastic sheeting manipulated into a fluid, curving form, a visual reference to the water that flows in nearby Blunn Creek.

"Frozen Flow" by Juan Deleon

Big Stacy Park, 700 E. Live Oak St.; through June 21.

Near the historic Stacy Park public pool, a platform of marine grade plywood planks mimics a moment of rippling waves and the undulation of the water’s surface, urging visitors to reflect on their relationship with the environment and especially water.

"Tree Hugger," by Brent Baggett

Schroeter Park, 11701 Big Trail; through June 27.

Made of cedar wood posts stacked and rotated on several axis points to create a curved, leaf-like structure, "Tree Hugger" features two openings on opposite sides. Visitors can step inside to be "hugged" by the sculpture.

"Binary Branch," by Jamie Panzer

Boggy Creek Greenbelt, 1114 Nile St.; through July 31.

Nature or technology? Jamie Panzer combines wood logs to form a grove of man-made trees with rectilinear branches based on binary patterns. Since its installation earlier this spring, every day Panzer has added to the binary-born trees, "growing" them with a kind of artistic artificiality.
