Flashpoint’s latest installation contains one feature that August-weary, overheated Washingtonians are certain to enjoy. Enter the ecologically friendly “Earth on Stone on Earth Is Naturally So” and head straight for the back corner, where a reconstructed turf hill beckons you to lie down on cool blades of grass that haven’t been reduced to scrub by the blazing sun. Above the grassy hill, an image of clouds and ambient colors is projected to music, and the lights dim in a cycle to represent night and day. But the hill is best enjoyed after a stroll around Karl Krause’s model planted roofs, which simulate anything from future eco-cemeteries to urban oases. One, with aquamarine parakeets in a cage atop it, reads “I know not where to rest perched in the sky,” while another contains a layer of not-so-biodegradable Styrofoam packaging peanuts. Behind the gardens is a series of photographs of artists buried up to their necks in soil, accompanied by text reflections of the experience. “It’s nothing like being dead,” states Mary Burger in Notes From the Ground, where she poetically describes watching the Golden Gate Bridge emerge from the fog. Other artists’ reactions range from rambling long texts to Speed Levitch’s pithy “I am proud to be biodegradable.” Flashpoint hopes to advance the ecological discourse with “The Eternal Human Habitat” (at 7 p.m. Tuesday, Aug. 21), a panel discussion about democracy, spirituality, and the environment. For green collectors considering a purchase, all proceeds will be donated to environmental groups. The exhibition is on view from noon to 6 p.m. Tuesdays through Saturdays, to Friday, Aug. 31, at Flashpoint, 916 G St. NW. Free. (202) 315-1305.
